How do I use MATLAB Compiler 4.1 (R14SP1) in 32-bit emulation mode on a 64-bit Opteron Linux platform?

Problem Description:

I am running MATLAB in 32-bit emulation mode on a 64-bit Opteron Linux machine. However, when I try using the MATLAB Compiler, I receive the following error:
Error: The MATLAB script returned a bad status while determining environment variables. There appears to be a problem with your MATLAB installation. You must fix the problem before mcc can work. Any messages from the script follow . . .

matlab: No MATLAB bin directory for this machine architecture.
How can I make the MATLAB Compiler work?

Solution: This solution applies to MATLAB Compiler 4.1 (R14SP1) only. For information about using MATLAB Compiler 4.2 (R14SP2) and later versions please see the related solution below. This error occurs because the MATLAB Compiler is not configured to be run on a 64-bit Opteron Linux machine. To work around this issue, try modifying the mbuildopts.sh file so that $ARCH is identified correctly, and append -m32 to the GCC flags. You can find an example of such a modified options file at the following website: http://www.mathworks.com/support/solutions/files/s1-XJ5PA/mbuildopts.sh
