Fix feature detection with multiple -arch flags

Browse Source 
When multiple -arch flags are used, the compiler invokes itself once for
each architecture. Apparently, input on stdin is consumed by the
compilation of the first arch and is no longer available to the
compilation of the second arch, which results in a build failure and the
potentially incorrect determination that a feature is not available. So
write the feature detection source to a file instead of using stdin.
