Hmm, so if my host's C compiler happens to be named gcc, I don't
have to remember, but if it happens to be named differently
(ncc, como, gcc-3, acc, ...) I need to remember?
Strange policy...

Well, that's the way all the packages using 'configure' work.
They pick up whatever is defined in your environment at
configure time.

And as I wrote, my most preferred solution would be something
like 'HOSTCC=gcc-3 make xyz_config'.  To achieve this, a simple
line like '[ $HOSTCC ] && echo "HOSTCC = $HOSTCC" >> config.mk'
in mkconfig would probably suffice.  But maybe there's another
(better) way.
