Using mac function interposition on x86_64-apple-darwin12 produces only 8

remaining g++ testsuite failures emitting ASAN:SIGSEGV messages compared to 10

seen in the g++ testsuite under x86_64 Fedora 15. Also on

x86_64-apple-darwin12, the switch from mach_override to mac function

interposition reduces the unexpected failures in the g++ testsuite from 841 to

323. This is still far more than seen under x86_64 Fedora 15 (which shows 107)

but still is a major improvement over mach_override.
