[Buildroot] [PATCH 2/2] package/gdb: use stat() privided by the system

[Romain Naour]

Use the same workaround [1] as gnulib use to get the original
definition of stat. Otherwise with musl toolchains, gnulib try to use
rpl_stat which is not defined.

Fixes:

I am confused by this patch. Why do we need that? The <sys/stat.h> on
my system doesn't test __need_system_sys_stat_h. Is this a workaround
to force gnulib to not provide its own stat() replacement ?

Why is gnulib misbehaving here ? We have tons of gnulib related hacks
in gdb.mk, and this start to pile up quite a bit. Why do we have all
those gnulib issues with gdb ? Why not with tons of other packages that
also use gnulib ?

Well rpl_stat() is supposed to be implemented by gnulib. So basically
gnulib tells gdb: please don't use stat() but my rpl_stat() wrapper,
but then gnulib doesn't provide rpl_stat().

Any idea what's happening here ?

There are too many questions here, I can't answer.
There are some (old) hack with coreutils like gl_cv_func_gettimeofday_clobber
which is in Buildroot since a long time. I can't tell for every gnulib based
packages...

As far I can tell, the regression has been introduced by this commit:
https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commitdiff;h=2441702a72f324e41a1624dc042b334f375e2d81

Well, Buildroot is using upstream musl and gdb. For both packages, we
have only very few patches:

  https://git.buildroot.org/buildroot/tree/package/musl/
  https://git.buildroot.org/buildroot/tree/package/gdb/8.1.1/

Note that we already have a number of gnulib related hacks in gdb.mk:

  https://git.buildroot.org/buildroot/tree/package/gdb/gdb.mk#n77

Upstream has fixed the issue. Could you try to backport upstream
commit 3c025cfe5efc44eb4dfb03b53dca28e75096dd1e instead, and see if it
solves the problem ?

Thanks!
