This caused a build failure for me.  I did a build on the GCC compile
farm (x86-64) and got:

/home/tromey/auto-test-gdb/gdb/bfd/elf32-microblaze.c: In function ‘microblaze_elf_check_relocs’:
/home/tromey/auto-test-gdb/gdb/bfd/elf32-microblaze.c:2135: warning: dereferencing type-punned pointer will break strict-aliasing rules
