    autoconf: Sanitize asm build for cross-compiling and --enable-*-bit
    
    Two fixes to the asm configuration:
     - Disable when the user is cross-compiling for x86 or x86_64 since it
       requires running an executable compiled for the target host.
     - If the user has specified --enable-32-bit on x86_64 or --enable-64-bit
       on x86, respect that and choose the correct asm architecture.
