To build this generic target, add the following flags to your configure line:
-b 32 -V 128 -A x86SSE1
-b 32 ensures that you build the 32-bit libraries, which is necessary,
since most older machines do not implement x86-64 (AMD64). The
-V 128 says that the original x86 ISA is extended by SSE1 only.
-A x86SSE1 selects an artificial architecture
providing you with portable (but slow!) architectural defaults.
