gcc: Enable OpenMP compiling and library
Multicore embedded systems are getting more and more common. Remove "--disable-openmp" from the GCC configuration options and always build libgomp. This only creates a "bigger" compiler but has no effect on the compiled binaries that don't use openmp. Tested a clean build on mips32el and arm7a, no problems encountered. Autoconf will not detect OpenMP after this change, because it will build and run a target binary on the build system. In order to use OpenMP, the variable ac_cv_prog_c_openmp=-fopenmp must be set.
