[PATCH] fortran, libgfortran: Avoid using libquadmath for glibc 2.26+

Hi! As mentioned by Joseph in PR105101, glibc 2.26 or later has on x86 (both -m32/-m64), powerpc64le, ia64 and mips support for *f128 math/complex APIs plus strtof128 and strfromf128, and these APIs allow us to avoid libquadmath for Fortran purposes on these architectures, replace *q math/complex
