    Build system: remove hack for Mac OSX in configure.ac (#10476)
    
    Cross-compilation on Mac OSX currently doesn't work. While building
    stage 1, the build system uses the `ar` for the target architecture
    instead of the `ar` for build/host architecture.
    
    The cause is a hack added in 24746fe78024a1edab843bc710c79c55998ab134
    (2010), to supporting bootstrap compilers built with older versions of
    Xcode. Xcode 4.3 started installing command line tools in a different
    location. Assuming this all behind us now, and the paths didn't change
    again (you never now), we can delete the hack.
    
    Deleting the hack fixes the cross compilation issue. Tested by Trac user
    jakzale.
