New experimental port of math/libquadmath

(In reply to Brooks Davis from comment #5)

According to your answer, it seems that the header is not sufficient and the
whole library is requested.

This new attachment removes 'USE_GCC', but of course it fails with clang:

libtool: compile:  cc -DHAVE_CONFIG_H -I. -I ./../include -O2 -pipe
-fstack-protector-strong -fno-strict-aliasing -MT math/fmodq.lo -MD -MP -MF
math/.deps/fmodq.Tpo -c math/fmodq.c  -fPIC -DPIC -o math/.libs/fmodq.o

extern __float128 acosq (__float128) __quadmath_throw;
       ^
./quadmath.h:48:27: error: __float128 is not supported on this target
…

If the support of 128 bits float get enabled, as suggested in comment #1, could
this compile?
