not that much I think. What would be needed is to store the compiler
name in the toolchain object and use the python strlen equivalent on
that instead of the hardcoded threes. And eventually pass the correct
values to CC and HOSTCC.

When I tried that, subprocess was barfing some (at least for me not
easily, [no I don't recall which one exactly] explainable) error, so I gave
up and created a script called *-gcc invoking clang and all was fine 
again ;)

So yes, it would be nice if buildman did not make such an assumption.
It is not strictly clang related as well, at least on FreeBSD you can 
install
many gcc compilers, which will be named gcc44, gcc45.. gcc5 etc.

As already mentioned, it is not related to this patch, it adds just another
hardcoded magic 3 value.

Regards,
Jeroen
