I bet instead of opts->x_linux_libc != LIBC_GLIBC it needs to use
#ifdef OPTION_GLIBC
if (!OPTION_GLIBC)
#endif
or so. I think the first committed patch actually used that
but used it in #if directive, which is wrong because it is something
that needs to be evaluated at runtime.
That doesn't work well either, because the *supports_split_stack
hooks have opts argument and OPTION_GLIBC doesn't take that.
So, here is a patch that introduces OPTION_*_P macros that take opts
as an argument and redefines OPTION_* using those (similarly to how
the option scripts create TARGET_*_P and TARGET_* macros).
