Build: Fix -fno-strict-aliasing on Xcode builds

Xcode is configured by default to turn on the strict aliasing optimization
through a separate project setting. This would cause the compiler to be called
with both -fno-strict-aliasing and -fstrict-aliasing. This change turns off
that project setting causing only the -fno-strict-aliasing flag to be provided
to the compiler.
