Do you have 32bit build of LLVM installed? I don't think distros ship the 32bit
llvm binaries, let alone development packages...  So you'll probably need to
build a 32bit version of LLVM (not an easy task).

If you provide a 32bit version of LLVM (and add it to the PATH) then it
--enable-32-bit will surely work.  But honestly this is brittle.

From my experience, the most reliable way of building 32bit versions of
software is to use a 32bit chroot.  There are several tools that help creating
and using a 32bit chroot from scratch for all distros.   Using -m32 only works
for simple software with very few dependencies.

At any rate, this is an issue with the build environment, not the build scripts
themselves, so there's nothing we can do about it, other than perhaps a warning
message saying that LLVM + --enable-32-bit will obviously require a 32bit
version of the LLVM development libraries installed.
