Subject: [PATCH] Libcompat: Set build tools in environment rather than make
 overrides.

This allows the CXX hack in r300917 for external GCC to work for
the lib32 build.  It is also the same pattern as the native
build uses by adding the tools into CROSSENV for external
toolchain, rather than make overrides.
