MFC r314505:
Split the ficl CFLAGS when they refer to an arch-specific include path.

This is a minimal attempt to keep consistency in the Makefiles so that
moving ficl to somwehere like contrib will be less error prone.

MFC r286368: Remove guards around overwriting loader.rc and menu.rc

There have been .local version of each for user modifications for some time
This allows users to receive future updates to these files

r261567: Build a 32-bit libstand under sys/boot/

A 32-bit libstand is needed on 64-bit platforms for use by various
bootloaders. Previously only the 32-bit version was built, installed
as /usr/lib/libstand.a.

A new 64-bit libstand consumer will arrive in the near future, so move
the bootloader-specific 32-bit version to sys/boot/libstand32/.

Explicitly link against this version in the 32-bit loaders.

r261614: Build a 32-bit libstand under sys/boot/ for ppc64

This change is equivalent to r261567 for i386/amd64.
