This is not true, upstream says:

It defaults to a 32-bit build; it will place the resulting file in the build-32 directory; if you want to have a 64-bit build, say "make BITS=64 all" instead.

You could easily support both 32 and 64 bits builds.

Also, it says nothing about working only on x86, maybe it works on arm, mips...

Also enable assembly for i386, mark port only for archs amd64/i386 accordingly.

It has inline assembly only for i386 and amd64. I think that rules out arm, mips, ... :-)

Then the message should not be "only builds and is supported on i386/amd64", which is already what ONLY_FOR_ARCH=amd64 i386 says, but "contains inline x86 assembly"

Update wording of ONLY_FOR_ARCH_REASONS to be more explicit.
