The cc- and binutils-wrapper's "infix salt" and <literal>_BUILD_</literal> and <literal>_TARGET_</literal> user infixes have been replaced with with a "suffix salt" and suffixes and <literal>_FOR_BUILD</literal> and <literal>_FOR_TARGET</literal>.
This matches the autotools convention for env vars which standard for these things, making interfacing with other tools easier.
