Commit Message
On aarch64-linux (debian 12), when running test-case gdb.base/corefile-buildid.exp, I get:
...
expecting exec file "debugdir-exec/.build-id/ec/f10ec5d39648774f8c35d3cf757c8db52f5163"

(gdb) FAIL: gdb.base/corefile-buildid.exp: exec: info files

The problem is that the test-case expect the build-id to be available in the
core file, while it isn't.
Fix this by detecting that the build-id isn't available in the core file using eu-readelf, as in
gdb.base/coredump-filter-build-id.exp.
Tested on aarch64-linux.

I was kind of surprised to find that gdb's test suite depends on a
non-binutils program like this, but whatever, the dependency is already
there.
Anyway this seems fine to me.
