[libcxx-commits] [libcxx] [libc++] Don't mark lgamma_r as noexcept on Fuchsia (PR #157710)

[Nico Weber via libcxx-commits]

https://github.com/nico created https://github.com/llvm/llvm-project/pull/157710

Building on Fuchsia is broken after #156547.
This disables the NOEXCEPT on Fuchsia to unbreak things. Hopefully we can come up with a more forward-compatible fix later.
