The conflict is very simple.

The ebuild says "must have 32 bits!"
You said "no zero zip nada 32 bits!'
The system says "screw this, you figure it out dude, I give up"

Solutions: There are 2, and they are mutually exclusive

1. Relax your stance and accept that some software out there that you
might want is 32 bits
2. Refuse to have 32 bits, so give up on llvm and clang. Find something
else and move on.

You must pick one of those two. There is no magic hidden solution that
magically lets you have something and also not have it.
