------------------------------+-----------------------------
 We already use GCC in-tree libraries for MPFR, MPC, GMP and zlib. Use them
 also for CLooG and ISL. This helps to ensure that the same target code is
 generated across host systems. It also helps to avoid GCC build issues in
 case future versions of ISL and CLooG available on the host system are
 incompatible to the GCC version picked up by the RSB for RTEMS.
