From 328de8e00e298f00d7ba6b25dc3950147e9642e6 Mon Sep 17 00:00:00 2001

Subject: Fix building on x86_64 with binutils 2.41

Newer versions of the GNU assembler (observed with binutils 2.41) will
complain about the ".arch i386" in files assembled with "as --64",
with the message "Error: 64bit mode not supported on 'i386'".

Fix by moving ".arch i386" below the relevant ".code32" directive, so
that the assembler is no longer expecting 64-bit instructions to be used
by the time that the ".arch i386" directive is encountered.

Based on similar iPXE fix:
