Ah, so it's enabling the Fortran support that makes it fail to build. I
see that it is including quadmath_weak.h only if HAVE_FLOAT128 is
enabled:
#ifdef HAVE_FLOAT128
# include "quadmath_weak.h"
#endif
I suppose PowerPC64 has HAVE_FLOAT128 enabled, and not other
architectures ?
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82292 has some context,
and concludes with "Yeah, I think this is user error.". Seems like
we're not passing the appropriate enable/disable libquadmath options.
