arch: Undefine possible architecture defines

Some compilers define the architecture to one leading to detecting
'1' as target architecture. Always undef the architecture name.

Compilers:
gcc version 4.6.3 (Debian 4.6.3-1) has '#define i386 1'
gcc version 4.5.3 (Broadcom stbgcc-4.5.3-1.3) has '#define mips 1'
