disable architecture check in generated module
The translate.diff patch disables the architecture check on the generated code.
This has been used by olpc developer Chris Ball with some success. However,
this could cause problems because it could allow illegal instructions to be in
the module. For example compile on i686 machine and generate conditional moves
that are not available on the i586 platform.
