Subject: [x86 patch] Fix UML init/do_mounts.h build failure



Fix stat.h to not use __i386__, but use BITS_PER_LONG. The UML architecture
in turn includes this file. This helps resolve one build failure in the
current UML code

Before the fix, the failure was

In file included from init/do_mounts.c:19:
init/do_mounts.h: In function 'bstat':
init/do_mounts.h:25: error: storage size of 'stat' isn't known
init/do_mounts.h:25: warning: unused variable 'stat'
init/do_mounts.h:33: warning: control reaches end of non-void function
make[1]: *** [init/do_mounts.o] Error 1
make: *** [init/do_mounts.o] Error 2
