'buildworld' not always pulling in /etc/src.conf

hi there,

i'm trying to run 'buildworld' on a fresh HEAD snapshot, but `make` is
failing with this error:

it seems for some reason gcc44 gets chosen at some point as compiler
instead of the base gcc. i DO have CC, CXX and CPP defined in my
/etc/make.conf so that gcc44 gets used for ports and other stuff.
HOWEVER /stc/src.conf also contains those three variables and they to
the base version of gcc. of course commenting out those variables in
/etc/make.conf fixes the problem, but if i'm not mistaken 'buildworld'
should use /etc/src.conf at all times and thus should be aware that i
want it to use base gcc.

i've attached my make.conf and src.conf.

cheers.
