The installation instructions seem to imply that GCC can be built without
having ISL and/or CLOOG installed, and the configure script accepts
--without-isl and --without-cloog.
But I can't build that. Reading the installation instructions makes me expect
that such a configuration would skip the building of the "graphite" loop
optimization machinery. What happens instead is that it's built anyway, but
the makefile aborts at the point where it tries to compile gcc/graphite.c
(because cloog/cloog.h does not exist).
Is this supposed to work?
