description:
Try 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" based on the ABI we are compiling for, not on
    based on the kernel the machine is running.

The "gnupg" package now builds for the 64-Bit API without extra tricks.
