When cross compiling, the word size of the compiler set via HOST_CC
must match the word size of the target. That's achieved by appending
"-m32" to BUILD_CC_ARCH if the target word size is known to be 32bits.
Unfortunately the current list of over-rides may not cover all cases.
Using SITEINFO_BITS is a more generic solution.
