Instead of traversing src/sys, as is done by newvers.sh for uname(1),
a full tree walk is done to prevent userland and/or modifications

New version is not compatible on supervisor mode with v1.9.1
(previous version).
Highlights:
o BBL (Berkeley Boot Loader) provides no initial page tables
anymore allowing us to choose VM, to build page tables manually
and enable MMU in S-mode.
o SBI interface changed.
o GENERIC kernel.
FDT is now chosen standard for RISC-V hardware description.
DTB is now provided by Spike (golden model simulator). This
allows us to introduce GENERIC kernel. However, description
for console and timer devices is not provided in DTB, so move
these devices temporary to nexus bus.
o Supervisor can't access userspace by default. Solution is to
set SUM (permit Supervisor User Memory access) bit in sstatus
register.
o Compressed extension is now turned on by default.
o External GCC 7.1 compiler used.
o _gp renamed to __global_pointer$
o Compiler -march= string is now in use allowing us to choose
required extensions (compressed, FPU, atomic, etc).

- bsd.compiler.mk: Must ensure that the CCACHE_WRAPPER_PATH comes first
in PATH.
- Makefile.inc1: Must prepend the CCACHE_WRAPPER_PATH into BPATH as it
overrides the PATH set in bsd.compiler.mk in sub-makes. The PATH
set in bsd.compiler.mk is not exported and doing so would cause it to
then override the BPATH set from environment. The only sane solution
is to prepend into BPATH as needed.
CCACHE_PATH could possibly be used for some of this as well.

This fixes 'make cleandir' to use the same ordering as 'make cleanobj'.
Meaning that SUBDIR will be recursed before the current directory is
handled. This avoids an 'rm -rf /usr/obj/usr/src/lib/libc' while
a child 'rm -rf /usr/obj/usr/src/lib/libc/tests' is being ran next,
or even removing the current directory and then recursing into a child
and using the 'missing OBJDIR' logic to remove files rather than the
directory.
The most ideal ordering here would be for 'cleanobj' and 'cleandir' to
simply remove the .OBJDIR and then not recurse at all. This is only
safe if it is guaranteed that all children directories have no orphaned
files in their source checkout and are only using obj directories. This
is usually safe from the top-level build targets and when using
WITH_AUTO_OBJ. Improving the build for those cases is coming.

- Only recurse on cleanobj/cleandir if there is no .OBJDIR being used.
If we don't recurse then bsd.obj.mk will just rm -rf the OBJDIR dir.
- When recursing on cleanobj/cleandir don't remove dependfiles/dirs
redundantly from the child and main processes. Meaning '.depend', and
'tags', and '.depend.*' will now only be removed from the main
process.
- Stop recursing on 'cleandepend' since the main process can handle
removing all files via the default glob patterns in CLEANDEPENDFILES.
- This reverts r288201, by readding recursion on 'cleanobj', due to
r291635 changing how bsd.subdir.mk handles recursion.
This is primarily targeting ESTALE NFS errors from rm(1) during a
buildworld but is also a performance optimization as both issues fixed
were redundant anyway.

Also switch the logic to enable this for any non-lld linker, since
filter library support is fairly simple and is very likely supported

Create libdl.so.1 as a filter for libc.so.7 which exports public dl*
functions. The functions are resolved from the rtld instead, the goal
of creating library is to avoid errors from the static linker due to
missed libdl. For static binaries, an empty .o is compiled into
libdl.a so that static binaries still get dl stubs from libc.a.
Right now lld cannot create filter objects, disable libdl on arm64
when binutils are not used.

In some cases bsd.linker.mk reports an error like:
make[4]: ".../share/mk/bsd.linker.mk" line 56:
Unknown linker from LD=ld -m elf32ppc_fbsd:"
For now change this to a .warning, and then assume GNU ld 2.17.50.
At present the linker type detection is used only for enabling build-id,
and we can carry on without it when type detection fails.
Also, show errors from ${LD} --version to aid in failure diagnosis.
Successful invocations of ${LD} --version produce no output on stderr
so this will not create any spam in non-failing builds.

LIBADD is only supported for in-tree builds because we do not install
share/mk/src.libnames.mk (which provides LIBADD support) into /usr/share/mk.
So if a partial checkout is done then the LIBADDs are ignored and no LDADD is
ever added.
Provide limited support for this case for when LIBADD is composed entirely of
base libraries. This is to avoid clashes with ports and other out-of-tree
LIBADD uses that should not be mapped to LDADD and because we do not want to
support LIBADD out-of-tree right now.

The problem is that some Makefiles will override LIBDIR to where they want
their library to install. bsd.libnames.mk will then use ${LIBDIR} to define
where *existing* libraries are. This then leads to looking for the
libraries in the *target* place rather than the *expected* place.
We may want to expand this (and all of the other *DIR variables in bsd.own.mk)
into something like what Ports has, a PREFIX and a LOCALBASE. PREFIX being
where things are being installed to and LOCALBASE being where they already are.
For now store the default expected LIBDIR into LIBDIR_BASE and use that for
library locations.
