The pattern rule %_defconfig doesn't support a pattern that includes a
/ because of the following weird make behavior. From the GNU make info
page:

  When the target pattern does not contain a slash (and it usually does
  not), directory names in the file names are removed from the file name
  before it is compared with the target prefix and suffix. After the
  comparison of the file name to the target pattern, the directory names,
  along with the slash that ends them, are added on to the prerequisite
  file names generated from the pattern rule's prerequisite patterns and
  the file name.

In other words, foo/bar_defconfig would depend on
foo/configs/bar_defconfig instead of configs/foo/bar_defconfig.

As a workaround, introduce an intermediate target that does contain a /
and where the pattern is at the beginning: %/.../defconfig. Since this
target does contain a /, the weird splitting of the pattern doesn't
occur and we can make that target depend on .../configs/%_defconfig.

It gets slightly more complicated still because chains of pattern rules
only work if they all have commands. So we need to add a dummy command
for the %_defconfig rule.

We currently have a list of toolchain configurations that are used by
the autobuilders at [1]. However, this makes it a little more difficult
for people to use these configurations, and also to have a different
list of configurations for different branches. For example if a new
architecture is introduced, the 2017.02.x branch doesn't have support
for this architecture yet so it shouldn't try to run those configs.

Therefore, include the autobuild defconfigs directly in Buildroot, so
they can be branched together with the rest. To avoid polluting the
configs/ directory too much, the autobuild defconfigs are kept in an
"autobuild" subdirectory.

The toolchain-configs.csv file also contained additional information:
the hostarch required by the toolchain binary, and the libc used. The
latter can be found in the defconfig itself, but the hostarch isn't in
there. To avoid still having to maintain a separate file, we just add a
BR2_HOSTARCH string to the defconfig file. When the defconfig is used
this string is completely ignored, but it can be used by the
autobuild-run script.

The changes to the autobuild-run script still have to be done. It's not
entirely trivial :-) so I didn't feel up to it.

Instead of this approach, I also considered adding the
buildroot-generated toolchains as external toolchains to the menus.
However, then there would still be a need for config files that specify
the subarch used, as well as e.g. STATIC. While with this approach the
entire toolchains/configs directory can be removed from
autobuild.buildroot.net.

How is the latter found in the defconfig? For example, with:

+BR2_HOSTARCH="x86"
+BR2_x86_pentium4=y
+BR2_TOOLCHAIN_EXTERNAL=y
+BR2_TOOLCHAIN_EXTERNAL_CODESOURCERY_X86=y

How will the autobuilder script know that it is a glibc toolchain?

So this BR2_HOSTARCH option needs to be added manually to the
defconfig: the defconfig are not directly the result of "make
savedefconfig", correct?

I also think this approach doesn't make much sense, because several of
the autobuild toolchains really don't make sense to have exposed in
Buildroot external toolchain menu. Some toolchain configurations only
exist just for the sake of testing interesting combinations.

Examples: the ARM no-thread toolchain, the basic PowerPC toolchain with
just C++ support, the ARM/glibc toolchain that intentionally always
uses the latest available version of gcc/binutils/glibc, etc.

Other than the issues raised above, I'm generally fine with the idea, I
think it makes sense. If we are going to change the architecture of the
autobuild-run there are lots of different things that could be done:

 - Testing different branches, like you are suggesting.

 - Change how "exceptions" are handled. Currently, people have to
   update their autobuild-run script to have the updated list of
   exceptions. It would be nice if this was not necessary, either by
   having the configuration generated by the autobuild server, or by
   having this list of exceptions in Buildroot itself so that it gets
   naturally updated when pulling the latest version of the source code.

Best regards,

Thomas

 I didn't think of that :-)

 But actually, as far as I can see, the only thing this is used for in the
autobuild-run script is to decide whether or not to add BR2_STATIC_LIBS=y. But
we can do that unconditionally - it will get removed by 'make oldconfig'.

 Indeed.

 I'm open to suggestions of a different approach, of course :-)

 One option would be to add further subdirectories for x86 and x86_64, but I
don't really like that.

 "issues" -> do you mean just the libc issue, or do you consider the
savedefconfig issue sufficiently severe that it needs a solution before committing?
