[PATCH] fix non-PC subarchs which were broken by i386 probe_roms change

The author apparently didn't understand that only the mach-default
include directory is included by fallback for header files only.  You
can't stick a .c file in mach-default and expect all subarchs to be able
to use it.

The correct fix is to put std_resources.c in the kernel directory and
give it its own Kconfig symbol for conditional compile so that subarchs
may choose to include it or not.
