fdlibm: Add workaround for building with older host compilers

Compiling fdlibm with old versions of gcc results in a compile
error because of legitimate code misdetected as an aliasing
violation.
As a workaround, we build the host version of fdlibm with
-fno-strict-aliasing, given we don't officially release host
compilers.
