I believe we established when libquadmath was added that this wasn't an 
option as large parts of the code are not assigned to the FSF.

(Longer-term it might make sense to support TS 18661-3 in GCC and glibc, 
so that libquadmath isn't needed when using new glibc as the functions are 
available in libm under TS 18661-3 names such as sinf128.)
