If you rework the preprocessor macros a bit you can generate both the enum and 
the array from the same list.

Something along the lines of
#define DEF_STUBS DEF_STUB(long_branch_any)[...]

#define DEF_STUB(x) arm_stub_##x,
enum{
  DEF_STUBS
}
#undef DEF_STUB

#define DEF_STUB(x) elf32_arm_stub_##x,
static const stub_def stub_definitions[] = {
 DEF_STUBS
}
