This is not going to help at all because it's checking the
name of the running system.

Sorry, my bad for being so terse but I'm quite in a rush.
Compilers, assemblers and linkers can dump their supported featureset
and the target options sometimes. This knowledge can be used to reveal
available systemlibraries and features by parsing this output and or
using this data (like paths to the crosscompiling environment) to
figure out what the real system is like.
