Thanks, Laurent. I want to run my binaries on a 64bit system, and I
would prefer to take advantage of its capabilities. But I have no use
for 64 bit pointers, which, in my case, are responsable for a large
size overhead. Since the m32 flg is not supported, I suppose the
target should be x32, which the musl site says is experimental (maybe
that information is outdated?)

I'll try and see if I'm able to grokk it!
