Change Details

As a transition aide, implement an alternative elfN_freebsd_fixup which is called for older binaries. This uses the old values and should allow an old userspace to work with a new kernel. TODOs: - Find out how a new rtld works with old binaries. We may need a seperate sysent for old binaries that calls an old rtld. - Put this code under ifdefs and remove the non-powerpc cases. NOTE: this has been lightly tested on mips64, but not on powerpc so I've only verified that binaries run the right fixup function.

As a transition aide, implement an alternative elfN_freebsd_fixup which is called for old powerpc binaries. Similarly, add a translation to rtld to convert old values to new ones (as expected by a new rtld). Translation of old<->new values is incomplete, but sufficient to allow an installworld of a new userspace from an old one when a new kernel is running.
