[Bug target/29398] New: configure should automatically set --disable-multilib on darwin

[howarth at nitro dot med dot uc dot edu]

Currently builds of gcc trunk can fail on darwin if the machine is a G4 or
non-EMT64 Macintel machine. It would be much better for configure to test if
-m64 works on the build machine and automatically use --disable-multilib if it
doesn't.
