Subject: [0/3] A few 32bit x86 fixes

I wanted to get rid of fpu->initialized but I did not understand the FPU
EMU code. So I decided to enable it and see how it works. Turns out it
doesn't work.

While #3 fixes this I propose the removal of it since probably nobody is
using it. While at, we could also remove the 32bit x86 code since it
makes things way more complicated.

Anyway, I tried fma() in userland and it worked. The only thing that
popped was not related to FPU and is addressed in #1.
