libgcc: Fix a warning/error in libgcc2.c [PR117624]
Since the switch to -std=gnu23 by default, float.h (included from
tsystem.h) defines INFINITY macro (to __builtin_inff ()), which now
results in a warning when compiling libgcc2.c which defines it
to something else (and, worse aarch64 compiles it with -Werror and
build fails).
libgcc2.c asserts INFINITY has the expected type which depends on
the macros with which libgcc2.c is being compiled, so guarding
the define with #ifndef INFINITY wouldn't work.
So this patch instead #undefs the macro before defining it.

* libgcc2.c (INFINITY): Add #undef before #define.
