which is the directory you're building in too, right?
i.e. the same as ./configure
So you're still building in the source directory.

You need TWO directories, one for the sources, and one you build in.

And why are you using with_xxx_lib instead of using --with-gmp ?

Try the makefile at http://advogato.org/person/redi/diary/229.html which will
do it all for you correctly:
make -f config-gcc.mk GCC_VERSION=4.6.0 GMP_VERSION=5.0.1
