I don't know offhand. There's also a mechanism for using external
toolchains.

However, ISTM that if 'make CC=xyzcc' ignores the setting and runs gcc
it's a bug. Even if nominally other compilers should be integrated
into the makefile framework, there are times when one wants/needs to
do 'make CC=../some/other/tooldir/gcc' and that ought to behave as
advertised.
