[PATCH] Fix building on x86_64 with binutils 2.41

[Michel Lind via B4 Relay]

From: Michel Lind <salimma at fedoraproject.org>

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:
