[Bug bootstrap/42785] New: error: impossible constraint in �easm�f

["monaka at monami-software dot com" <gcc-bugzilla at gcc dot gnu dot org>]

I got "error: impossible constraint in ?easm?f" on the build time.
It only happens building with "-arch ppc" option. There is no errors in case I
choice "-arch i386"/"-arch x86_64".
