Fix build problems on MacOS 10.7 (Lion)

On MacOS 10.7 (Lion) with Xcode 4.1 installed, the default
C compiler is llvm-gcc-4.2. That compiler compiles beam_emu.c
incorrectly, resulting in an emulator that will not start.

The problem can be worked around by turning off all optimizations,
but that will significantly degrade the performance of the run-time
system. The problem can also be worked around manually like this:

  CC=gcc-4.2 ./configure

To allow a working system to be built "out of the box", have
the configure script set up the emulator Makefile so that gcc-4.2
will be used to compile beam_emu.c if the default compiler is
llvm-based. All other C files will still be compiled with the
default compiler.
