Title: mkvalidator: fix compile error with XCode-4.3

Mkvalidator suffers the same problems as mkclean, a hardcoded
path to /Developer and a version-min=10.6. This removes a broken
inreplace, adds a patch to not force an SDK path on 64bit systems
nor a minimum version. Unreported, but identical to mkclean that
was reported. Fixes compile errors on Lion.
