[PATCH] D78687: [Fuchsia] Build compiler-rt builtins for 32-bit x86

[Petr Hosek via Phabricator via cfe-commits]

Herald added a project: clang.

While we don't support 32-bit architectures in Fuchsia, these are needed
in the early boot phase on x86, so we build just these to satisfy that
use case.
