gcc-4.9: Fix various _FOR_BUILD and related variables

This patch is based on the patch for gcc-5.2 (41cbfd7af60f93a4bd496b7b6bf477215a286950)

When doing a FOR_BUILD thing, you have to override CFLAGS with
CFLAGS_FOR_BUILD. And if you use C++, you also have to override
CXXFLAGS with CXXFLAGS_FOR_BUILD.
Without this, when building for mingw, you end up trying to use
the mingw headers for a host build.

The same goes for other variables as well, such as CPPFLAGS,
CPP, and GMPINC.
