Bootloaders for powerpc are not built as position independent
code. Since bsd.prog.mk is used for building, when PIE is enabled,
the PIE flags are added and that causes the build to fail.
Adding MK_PIE=no stops bsd.prog.mk from adding PIE specific flags.

Follow-up to r353959 and r368070: do the same for other architectures.
arm32 already seems to use its own .fnstart/.fnend directives, which
appear to be ARM-specific variants of the same thing. Likewise, MIPS
uses .frame directives.

Due to the way u-boot for 32-bit powerpc is compiled, the interrupt code
assumes that the GOT pointer (r30) on u-boot is always intact.
When making syscalls to u-boot, ensure that we have restored r30 like we
found it before we enable interrupts to prevent u-boot from crashing if a
timer interrupt was pending.
This fixes ubldr on e500 qemu (assuming you have recompiled qemu's u-boot
with API support!)

This was committed due to what was later diagnosed as an msdosfs bug
preventing in-place strip. This bug was fixed in r352564, and we agreed to
keep the workaround in for a bit to allow the driver fix a suitable amount
of propagation time for folks building/installing powerpc/ubldr, seeing as
how we were not in any hurry to revert.
Summary:
Install's strip capability, by way of strip(1), doesn't seem to work
correctly on msdosfs, and instead ends up truncating the resulting
binary to 0-length. As a workaround, don't strip ubldr(8). This
fixes installworld on Book-E ubldr-based platforms, which prior to this
would need to manually install ubldr separately after installworld, in
order to have a functional ubldr.
The same thing could be done on PowerNV platforms that use msdosfs /boot
volumes, since loader and loader.kboot, etc, all get truncated to 0 on
install. However, PowerNV does not use loader, instead loading from
petitboot, so it's not really necessary at this time.

Summary:
Now that mpc85xx can boot via ubldr, move ubldr to a separate
filesystem, mounted on /boot/uboot, so that a fresh install can boot correctly.

preference to LIBFICL{,32}. LIBFICL{,32} are now always defined, but
LDR_INTERP{,32} is defined empty when building w/o forth (aka the
simple interpreter) and defined to LIBFICL{,32} when we are building
forth.
MK_CTF, MK_SSP, MK_PROFILE, NO_PIC, and INTERNALLIB are always the
same, so set them in defs.mk. MAN= is common, so set it here too.
This removes a lot of boring repetition from the Makefiles that added
almost no value.
HELP_FILES is a loader only thing, so move it to loader.mk. Only
generate the help file if HELP_FILES is defined. Adjust Makefiles to
new convention. Fix a few cases where ${.CURDIR}/ was missing
resulting in missing bits from the help files.

simd / no float stuff is centeralized here. Also centralise
-ffreestanding since it is specified everywhere.
This, along with a change to share/mk/bsd.cpu.mk to include -mno-avx2
in CFLAGS_NO_SIMD should fix building for newer machines (eg with
CPUTYPE=haswell) where clang was generating avx2 instructions.
