[PATCH] Fix the build-id option for GCC default configuration

[Bernd Edlinger]

It is possible that the compiler is configured to do
so automatically, but at least for GCC the configure option
--enable-linker-build-id is not enabled by default.
So the option -Wl,--build-id should be used regardless
of which compiler is used.
---

This prevents the following test failures when
GCC is used in default configuration:

FAIL: gdb.base/build-id-seqno.exp: find debuginfo with a single build-id file: debuginfo was read via build-id
FAIL: gdb.base/build-id-seqno.exp: find debuginfo with 4 build-id files: debuginfo was read via build-id
