So, here is a patch that parallelizes the longest test chunks
on x86_64-linux some more.

libstdc++ testing is now split into 10 jobs, roughly equally sized
(used to be 4), check-gcc testing is now split into 10 jobs too (used to
be 7, but the new division attempts to be more balanced, fastest
job takes for me 8 minutes and longest job takes 11), and check-gfortran
is now run in 7 jobs instead of 4.  This should make these more comparable
e.g. to check-g++ chunks etc.

Regtested on x86_64-linux, verified the merged *.sum files are identical.
Ok for trunk?

2011-06-20  Jakub Jelinek  <jakub@redhat.com>

	* Makefile.in (dg_target_exps): Set.
	(check_gcc_parallelize): Parallelize gcc testing into 10 jobs
	instead of 7, try to divide it more evenly.

	* Make-lang.in (check_gfortran_parallelize): Parallelize dg.exp
	into 6 jobs instead of 3.

	* testsuite/Makefile.am (check_DEJAGNU_normal_targets): Add
	check-DEJAGNUnormal[4-9].
	(check-DEJAGNU): Split into 10 jobs for parallel testing instead of 4.
	* testsuite/Makefile.in: Regenerated.
