gcc: fix c++ headers when same triplet cross compiling

Browse source 
When build platform and host platform differ, but have the same
triple, the code in nixpkgs will consider it a cross compilation,
but gcc won't. This will lead some derivations to look for c++
headers in the wrong place. To solve this always output the headers
in the non-cross location, like we do for the other gcc headers
already.
