Revert r267233 for now. PIE support needs to be reworked.

1. 50+% of NO_PIE use is fixed by adding -fPIC to INTERNALLIB and other
   build-only utility libraries.
2. Another 40% is fixed by generating _pic.a variants of various libraries.
3. Some of the NO_PIE use is a bit absurd as it is disabling PIE (and ASLR)
   where it never would work anyhow, such as csu or loader. This suggests
   there may be better ways of adding support to the tree. Many of these
   cases can be fixed such that -fPIE will work but there is really no
   reason to have it in those cases.
4. Some of the uses are working around hacks done to some Makefiles that are
   really building libraries but have been using bsd.prog.mk because the code
   is cleaner. Had they been using bsd.lib.mk then NO_PIE would not have
   been needed.

We likely do want to enable PIE by default (opt-out) for non-tree consumers
(such as ports). For in-tree though we probably want to only enable PIE
(opt-in) for common attack targets such as remote service daemons and setuid
utilities. This is also a great performance compromise since ASLR is expected
to reduce performance. As such it does not make sense to enable it in all
utilities such as ls(1) that have little benefit to having it enabled.

Regen after r270168
Use bsd.lib.mk here as all other csu Makefiles do.

This effectively reverts r124752.

There's no reason this should be different. It resulted in needing NO_PIE in
the original opt-out NO_PIE commit as this was not using the proper framework.

Avoid showing stale errors when nmount(2) fails.

Sometimes nmount(2) will fail without setting errmsg. The previous (ignored)
error would then be shown as the reason for the failed call if the next
nmount(2) also fails without [ENOENT,ENOTSUP].

An example is when there is a tmpfs mounted with -o size. vfs_filteropt() adds
'size' as an error in errmsg due to 'size' not being in tmpfs_updateopts. Then
tmpfs_mount returns [ENOTSUP] from nmount(2), which is then ignored. The next
call may race with an unmount causing an invalid [EINVAL] that then does log an
error, with the tmpfs errmsg.

The race itself is a separate issue to fix as it is expected to have an
[ENOENT] returned instead.

In this example the mount being shown is actually nullfs, not tmpfs that the
error is from.

  mountd[740]: can't delete exports for /poudriere/data/.m/exp-head-commit-test-devel/04/.npkg: Invalid argument mount option <size> is unknown

It should only show:

  mountd[740]: can't delete exports for /poudriere/data/.m/exp-head-commit-test-devel/04/.npkg: Invalid argument

Don't stop other legs of a parallel build due to a failure in make_check.
The whole point is to see if there's any failure, which is handled by
building a newer version of make.

Add arch-specific macro SFBUF_PHYS_DMAP(), which should translate the
physical address of the page to direct map address, in case
SFBUF_OPTIONAL_DIRECT_MAP returns true.  The case of PowerPC AIM
64bit, where the page physical address is identical to the direct map
address, is accidental.
