It is built in libgcc_s.so and libgcc_eh.a to simplify transition.
It is enabled by default on arm64 (where we previously had no other
unwinder) and may be enabled for testing on other platforms by setting
WITH_LLVM_LIBUNWIND in src.conf(5).
Also add compiler-rt's __gcc_personality_v0 implementation for use with
the LLVM unwinder.

This will ensure that the variable was not set as a make override, in
make.conf, src.conf or src-env.conf. It allows setting the value in
src-env.conf when using WITH_AUTO_OBJ since that case properly handles
changing .OBJDIR (except if MAKEOBJDIRPREFIX does not yet exist which is
being discussed to be changed).
This change allows setting a default MAKEOBJDIRPREFIX via local.sys.env.mk.

for libraries that follow the soft float ABI. It's only supported on
armv6 as a transition to the new hard float ABI, so mark as broken
everywhere else.
For determining the compiler version, quote the string to be echo'd,
otherwise the command might fail. This is because clang -v now results
in the following:
FreeBSD clang version 3.8.0 (trunk 256633) (based on LLVM 3.8.0svn)
The second "3.8.8svn)" string tripped up the shell command.

POSIX requires for the c99 compiler.
(In fact, our c99(1) already ignores -lxnet; but our make(1) doesn't set
${CC} correctly, and our cc(1) treats xnet like any other library.)

LLDB is usable for userland core file and live debugging on amd64, and
for userland core file debugging on arm64. In general it works at least
as well on FreeBSD as our in-tree gdb version, so enable it by default
to allow for broader use and testing.
An LLDB tutorial is available at http://lldb.llvm.org/tutorial.html, and
a table mapping GDB commands to LLDB commands can be found at
http://lldb.llvm.org/lldb-gdb.html .
LLDB also has some level of support for FreeBSD on arm, mips, i386,
and powerpc, but is not yet ready to have them enabled by default.

This is not wrong, but was unexpected. Using <empty>:H results in '.' which
then using the rest of the conversion was added in RELDIR. This was also
causing an empty _DP_DIRDEPS to resolve to SRCTOP for DIRDEPS.

system call information such as system call arguments. Initially this
will consist of pulling duplicated code out of truss and kdump though it
may prove useful for other utilities in the future.
This commit moves the shared utrace(2) record parser out of kdump into
the library and updates kdump and truss to use it. One difference from
the previous version is that the library version treats unknown events
that start with the "RTLD" signature as unknown events. This simplifies
the interface and allows the consumer to decide how to handle all
non-recognized events. Instead, this function only generates a string
description for known malloc() and RTLD records.

These use ld(1), effectively -nostdlib, and don't need any of these
normal dependencies.
kmod builds also define PROG so just checking for KMOD here seems to be
the easiest to handle it.

Debug data files are now built by default with 'make buildworld' and
installed with 'make installworld'. This facilitates debugging but
requires more disk space both during the build and for the installed
world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes

This will save time generating dependency files that we didn't expect
due to cases where SRCS!=OBJS or for building custom targetted objects
in Makefiles that do not end up in the DEPENDOBJS list.
This uses a bmake trick to modify CFLAGS based on ${.TARGET}. A
.PARSEDIR check is done for the sake of MFC safety.

Rather than try to guess at all of the OBJS variables just use SRCS
using the same patterns that mkdep does. This also fixes a mistake
where dependencies were being generated with FAST_DEPEND when they were
not for mkdep. This happens when OBJS!=SRCS as is the case in
gnu/lib/csu where SRCS has 1 file and OBJS has several other files that
does not even contain the 1 SRCS file. Generally in these cases the
OBJS have custom dependencies defined in their Makefile. If we generate
dependencies for those and then load a .depend file, then .IMPSRC may
contain duplicate sources and lead to errors such as:
cc: error: cannot specify -o when generating multiple output files

My changes in r291635 broke 'make install*' for DIRDEPS_BUILD but also
revealed that some other targets were not guaranteed to be created if
there was a SUBDIR defined. One example is 'installfiles' was never
defined if SUBDIR was not empty.

The problem was that 'afterinstall' was not coming after SUBDIRs were
installed which was the expectation at least in sys/modules for kldxref.

This would cause it to be included everywhere in the build since it is
