On my machine, the -m32 flag disables SSE instructions, and since this build
uses some system headers that, on my machine, contain inline assembly with SSE
instructions, this will not compile.

Can you add the -msse flag to these three lines, which manually re-enables these
SSE instructions so that they can compile on systems such as mine?

Done.
