ppc configurations that have -mstrict-align enabled by default fail

This was regstrapped on x86_64-linux-gnu, tested with a cross to a
ppc64-vxworks7r2 configured with -mstrict-align enabled by default,
and I'm now also regstrapping on ppc64-linux-gnu just to be sure.
Ok to install?
The -mstrict-align option is defined in sysv4.opt, which is not used in
all configurations (like, powerpc64-darwin*, and the AIX configs).
this works for me on powerpc-darwin, I haven’t tried to test AIX.
