[Buildroot] [PATCH 1/3] package/strace: bump to 4.21

[Buildroot] [PATCH 1/3] package/strace: bump to 4.21

[Romain Naour]

Switch to the new upstream url [1].

Use new --disable-mpers option instead of
st_cv_m32_mpers=no and st_cv_mx32_mpers=no

Restore previous mpers check behaviour (strace < 4.21) by specifying
--enable-mpers=check. Otherwire strace enforces mpers support by
default which require a specific compiler. See [2].

Even if there are 4.21 archive file hashes provided by sourceforge, don't
use them since we just switched to github.

As far as I know, the main (only?) reason for a libunwind dependency
is to support 'strace -k' to get callstack info. Perhaps it would be
useful to update the Config.in file to hint about this, i.e. that
users should enable libunwind manually if they want 'strace -k'
support.

In our local tree, I had added a config option to strace for that, but
perhaps that is overkill?

Ok, why not.

Most packages optional dependencies are handled like this, otherwise we have to
maintain one config option for each optional dependencies.

Are you saying that you have changes in your local tree on packages
available in upstream Buildroot, and you did not submit such
changes ? :-)

Haha, yes indeed :-) But you may be glad to hear that I already made a
list of such changes that should be upstreamable, and plan to tackle
the upstreaming after merging 2018.02!

The code is ready, but the drop was postponed due to other issues...

I'll get to it, don't worry :)

I've updated the Config.in help text to indicate that libunwind should
be enabled to get "strace -k" support, as suggested by Thomas DS. And
then I've applied. Thanks!

In fact those patches are not necessary if you pass
--with-libiberty=check. In this case, it doesn't fail at the first
demangle.h check, and moves on to the next header file location.

So I've fixed that up, dropped the patches and AUTORECONF = YES, and
applied to next. Thanks!
