You can probably do something like this in a Makefile:

.c.o:
        if test -z "`sed -e '/COMPILE_ME_WITH_GCC/!d' $<`" ; then \
                gcc -c -o $@ $< ; \
        else \
                tcc -c -o $@ $< ; \
        fi

And then put /* COMPILE_ME_WITH_GCC */ in those files you want to compile 
with gcc. The others will be compiled with tcc This is untested, I might 
have missed a ; somewhere, but this is the general idea.
