--- Comment #15 from Tamar Christina <tnfchris at gcc dot gnu.org> ---
This patch is causing the aarch64 and arm baremetal builds to fail because
newlib doesn't seem to have lstat.

/tmp/aarch64-none-elf/build/src/gcc/libbacktrace/elf.c: In function
'elf_is_symlink':

/tmp/aarch64-none-elf/build/src/gcc/libbacktrace/elf.c:659:7: error: implicit
declaration of function 'lstat'; did you mean 'stat'?
[-Werror=implicit-function-declaration]

   if (lstat (filename, &st) < 0)

       ^~~~~

       stat
