--- Comment #147 from Kazumoto Kojima <kkojima at gcc dot gnu.org> --- (In reply to John Paul Adrian Glaubitz from comment #145) Looks that some error occured durring configuring target libgomp. Unfortunately we can't see what is going on from that log. If /<<PKGBUILDDIR>>/build/sh4-linux-gnu/libgomp/config.log exists, it might have more details.
