build evbppc modules in 3 different flavours:

- oea (default)
- ibm4xx
- booke

this, together with earlier machine_module[] work, should allow evbppc
platforms to use modules.

Switch evbppc/ibm4xx to generic evbppc (same as oea) kernel modules.

I've confirmed that kernels similar to amd64/conf/MODULAR work fine
both on 403 and 405.

XXX
Unfortunately, we cannot immediately switch evbppc/booke to generic
kernel modules yet; it has its own intr.h implementation.

the x86 xen and non-xen modules are identical,
so remove the unneeded extra copies.
Xen kernels now use the same modules as native kernels.

Rename module directory for ibm4xx from /stand/powerpc-4xx to
/stand/powerpc-ibm4xx to match with what we set in evbppc_machdep.c:

https://nxr.netbsd.org/xref/src/sys/arch/evbppc/evbppc/evbppc_machdep.c#86

(And we use ibm4xx not 4xx for directory in sys/arch/powerpc.)

Note that we had never enabled MODULAR for ibm4xx yet; kernel with
MODULAR option was unable to build. This should be why this discrepancy
had never been found until today...

Don't build the module sets for non-pae-32bit-pv. Noted by John D. Baker
on port-i386@, thanks.

Add support for build mips64 kernel modules as N32

branches: 1.2.4;
Add the infrastructure for MODULAR support for Xen kernels. At
the moment, this can only load very simple modules due to missing
symbols. It is being add at this time to make pullups to the
netbsd-7 branch easier. It is not enabled by default in any kernels.

Put GCC/GAS options under ACTIVE_CC == "gcc".

Don't set -mmultiple or -mno-string for PowerPC, the difference is too
small to really matter and it sometimes even increases the size.
