i don't completely understand what is happening here - i386 presumably
refers to the architecture, not to the very-low-level details of
the architecture, so there should not be anything specific to
one processor of the family in the flags passed to the compiler.

Could it be that it's a compiler bug instead (or something in
your /etc/make.conf which is forcing compiler-specific optimizations
but only for a part of the build or the libraries) ?
