That's correct, as languages other than C are not built until stage3
when bootstrapping.  You can --disable-bootstrap and you should end up
with all enabled languages built with the preexisting host compiler.  In
that case you might have to set plain CFLAGS instead of STAGE1_CFLAGS
since there is no staging, but double check the generated makefile to be
sure.
