Aarch64 build fails now due to -Werror being on by default and both
libgcc2.c and float.h define INFINITY (after the switch over to C23 by
default).

../../../gcc/libgcc/libgcc2.c:2676:9: error: ‘INFINITY’ redefined [-Werror]
 2676 | #define INFINITY        CONCAT2(__builtin_huge_val, CEXT) ()
      |         ^~~~~~~~
In file included from ../../../gcc/libgcc/../gcc/tsystem.h:45,
                 from ../../../gcc/libgcc/libgcc2.c:27:
/home/builder/worker/gcc-fedora-arm64/gcc-build/gcc/include/float.h:262:9:
note: this is the location of the previous definition
  262 | #define INFINITY        (__builtin_inff ())
      |         ^~~~~~~~
cc1: all warnings being treated as errors
make[2]: *** [Makefile:512: _divhc3.o] Error 1

Should we do #undef INFINITY in libgcc2.c? change all of the uses of
INFINITY to something else?

Thanks,
Andrew
