sh4 needs much time in a test of gcc.
It is a test of libstdc++ to spend much time in that (about 28 hour).
I want to disable sh4's test of libstdc++ in the same way as arm
Please enable sh4 in libstdc++-no-testsuite.diff.
I attached 2 patch in this mail.
This patch fix this bug.
This patch cleanup and drop hppa from
because this does not use in debian/rules.patch.
Currently, this is enable in arm, mipsel and sh4.
