  To: gentoo-dev; +Cc: toolchain, Michał Górny

Make tc-getBUILD* functions respect host variables (CC & co.) when
not cross-compiling. This removes the necessity of overriding BUILD_*
along with the regular variables on the systems that are not concerned
about cross-compilation, and does not change the behavior for those
which are.

Closes: https://bugs.gentoo.org/630282
