Fix GCC9 warning on elf32-arm.c:elf32_arm_final_link_relocate
Fedora Rawhide has just switched to GCC9, and now GDB doesn't compile
because of a BFD warning:
BUILDSTDERR: ../../bfd/elf32-arm.c: In function 'elf32_arm_final_link_relocate':
BUILDSTDERR: ../../bfd/elf32-arm.c:10907:10: error: absolute value function 'labs' given an argument of type 'bfd_signed_vma' {aka 'long long int'} but has parameter of type 'long int' which may cause truncation of value [-Werror=absolute-value]
BUILDSTDERR: 10907 | value = labs (relocation);
BUILDSTDERR: | ^~~~
You can take a look at the full build log here:
https://kojipkgs.fedoraproject.org//work/tasks/4828/32174828/build.log
The fix is (apparently) simple: instead of using 'labs', we should use
'llabs', since we're passing a 'bfd_signed_vma' to it, which is at
least a 'long long int', as far as I have checked. This is what this
patch does.
bfd/ChangeLog:

* elf32-arm.c (elf32_arm_final_link_relocate): Use 'llabs' instead
of 'labs' (and fix GCC warning).
