[01/11,gdb/testsuite] Add gdb.base/fission-macro.exp

  Starting with gcc commit 80048aa13a6 ("debug/111409 - don't generate COMDAT
macro sections for split DWARF"), available from release gcc 14.1 onwards, gcc
produces a usable dwarf-5 32-bit .debug_macro.dwo section.

Add a test-case excercising this.

Tested on x86_64-linux.

Tested test-case using a current gcc trunk build, and gcc 14.

I went ahead and pushed this patch, since it only adds a test-case.

Thanks,

As you may have noticed, this patch was flagged by our CI on arm:

I've also noticed:
get_compiler_info: gcc-15-0-0

(which is expected, this CI loop is using trunk GCC)

Does this help?

Hi Christophe,

Thanks for the info.

Indeed I already noticed it, and filed this PR ( 
https://sourceware.org/bugzilla/show_bug.cgi?id=31897 ) to track it.

I managed to reproduce it, and AFAICT it's fixed by the following patch 
in the patch series (something I didn't realize when committing, because 
this FAIL occurs only on 32-bit targets).

Sorry for the noise.

Thanks,
- Tom
