[patch+8.0] release branch: Fix: --enable-werror

Hi,

gdb-8.0-branch
./configure --enable-werror --enable-targets=all
aarch64-tdep.c:3045:13: error: ‘void selftests::aarch64_process_record_test()’ declared ‘static’ but never defined [-Werror=unused-function]
arm-tdep.c:9601:13: error: ‘void selftests::arm_record_test()’ declared ‘static’ but never defined [-Werror=unused-function]

OK for check-in?

Please do not tell me release branches do not support --enable-werror as this
is due to a sourcebase bug, not due to some unexpected compiler
incompatibility.

Sergio: Shouldn't it be also buildbot-tested?

OK.

Certainly.

Sounds like a good idea.

Yes, it should.  We have an Arch64 builder managed by Yao.  It should
be possible to set up builders for the 8.0 branch.

FYI no specific arch is required for the builder, it even happened for me on
my x86_64.  These were *-tdep.c files so --enable-targets=all is enough to
trigger it.

Sure more archs would make better coverage even for nat/* files.
