Lack of 64bit support breaks -run

[Russ Lewis]

Since dmd can't link properly on AMD64 linux, I can't use -run.

It has occurred to me that one (simple) solution to this would be to add 
an argument to dmd which it would pass to gcc, so that I could pass 
-m32.  I tried using -L, but that passes the argument
	-Xlinker -m32
to gcc rather than what I'm attempting to pass, which is simply
	-m32
