[libc-commits] [libc] [libc][math][c23] Temporarily disable asinpif16 C23 math function (PR #150754)

[via libc-commits]

https://github.com/overmighty created https://github.com/llvm/llvm-project/pull/150754

The MPFR test uses `mpfr_asinpi` which requires MPFR 4.2.0 or later, but
the Buildbots are running an older version of MPFR.

See https://lab.llvm.org/buildbot/#/builders/104/builds/27743 for
example.
