Iain Sandoe discovered that on intel darwin9, the asan testsuite suffers
hundreds of
failures due to the absence of dispatch calls (Grand Central Dispatch) prior to
darwin10.
The attached patch disables building libsanitizer on darwin8 and darwin9 until
upstream
decides to support the earlier darwin releases. Bootstrap and regression tested
on
x86_64-apple-darwin12. Okay for gcc trunk?
