Try again to fix Mac OS X Snow Leopard ABI issue (32-bit vs. 64-bit):

1.) Always set the "ABI" variable.
2.) Default to 64-bit mode if the machine is able to run 64-bit binaries.
    This seems to match the default behavior of Xcode (Apple's toolchain).
3.) Set "LOWER_ARCH" so it automatically evalutes to the correct value
    based on the ABI we are compiling for, not on based on the kernel
    the machine is running. This even works properly if the ABI is
    set in "/etc/mk.conf" or on the command line.

Thanks a lot to OBATA Akio for providing the crucial hint to get
this working properly.
