- let this work on powerpc. requires gcc >= 4.3, and I had to patch
away a .gnu_attribute that isn't supported with as(1) from any in-tree
binutils version (was added in 2.18 which is under GPLv3).
- add ONLY_FOR_ARCHS based on the list of arch which luajit supports.
No point even trying to build on unsupported arch, but we should allow
it to build on arm/mips64* to see if it works there.
My armish box isn't working any more, so I can't test arm.
macppc is tested and produces same results for the test programs
in the lua 5.1 distribution as normal lua does.
OK?
