On debian, suse, fedora etc - it should be possible to use a really simple
configure.

git clone git://gcc.gnu.org/git/gcc.git
cd gcc
./contrib/download_prerequisites
mkdir build
cd build
../configure --enable-languages=m2 --prefix=$HOME/opt
make -j $(nproc)
make install

is often what I use (maybe add --disable-bootstrap / multilib).
But no need to specify libgm2 etc as that is automatically built when
requesting m2 (I suspect a number of the make targets above are
internal).  Note that the ./contrib/download_prerequisites is quite
useful as (for modern hardware/os you don't have to worry about isl
versions and others)
