toolchain.eclass: ppc64-musl: Disable libquadmath
* --disable-libquadmath is needed to avoid GCC PR 116007.
* --disable-libquadmath-support is needed for Fortran to build, as GCC
upstream requires a weak header when float128 is available.
* --with-long-double-128=no explicitly disables all Float128 support.
[sam: Fix whitespace.]
