+Subject: [PATCH] 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:
