musl: use correct long double abi by default
On powerpc and s390x the musl ABI requires 64 bit and 128 bit long
double respectively, so adjust the default.
gcc/ChangeLog:
2019-11-18 Szabolcs Nagy <szabolcs.nagy@arm.com>
* configure.ac (gcc_cv_target_ldbl128): Set for powerpc*-*-linux-musl*
and s390*-*-linux-musl* targets.
* configure: Regenerate.
