b3a9841934 Link libgcc_s against compiler-rt on ARM EABI. This allows us to use all of
the symbols in compiler-rt, including the ones not available in the old
libgcc. This fixes the build with clang which generates calls to funstions
that are missing from libgcc_s.

d7aa5f02d0 In kthr.c, obtain the address of the PCB for threads that were running
on a core, when the core was stopped, by calling kgdb_trgt_core_pcb().
This has 2 advantages:
1.  We don't need to include a machine-specific header anymore and as
    such kthr.c is truly machine independent. This allows the code to
    be used in a cross-debugger.
2.  We don't need to lookup stoppcbs in generic code when it's an
    inherently target-spicific symbol. It does not exist for ia64.

Implement kgdb_trgt_core_pcb() for all architectures, except ia64, by
calling a common function called kgdb_trgt_stop_pcb(). This function
differs from kgdb_trgt_core_pcb() in that it gets the size of the PCB
structure as an argument and as such remains machine independent.

On ia64 the PCB for stopped cores is in the PCPU structure itself.
This for better scaling. The implementation of kgdb_trgt_core_pcb()
for ia64 uses the cpuid_to_pcpu[] array to to obtain the address of
the PCB structure.

4792733bb8 Fix some symbol version mismatches between libstdc++ and libsupc++/libcxxrt
that were causing the runtime and STL libraries to see different versions of
various classes and functions when libstdc++ is used as a filter.

Note: This changes the ABI for libcxxrt, but libcxxrt is currently only in
-STABLE for testing and is not used by anything unless explicitly enabled by
the end user.  No default compiler configurations use it.

libc++ will need to be recompiled after this change.  make buildworld will do
this automatically, but make in lib/libc++ will not necessarily work unless the
new libcxxrt is installed first.

af0dd31fc4 Import new (BSDL) device tree compiler. Now built by default, so that it can't
be used on the host system (and not installed on the device, if required).  The
GPL'd one is still available if there are any devices that need it (make
universe passes with it, including kernels that use fdt, but there may be some
out-of-tree ones).  WITH_GPL_DTC can be used to select the old one, for now.

Probably won't be MFC'd, but we'll remove the GPL'd version in head after the
new one has had a lot more testing and ship it in 10.0.

Marcel Moolenaar
0815243c39 Add support for bmake. This includes:
1.  Don't do upgrade_checks when using bmake. As long as we have WITH_BMAKE,
    there's a bootstrap complication in ths respect. Avoid it. Make the
    necessary changes to have upgrade_checks work wth bmake anyway.
2.  Remove the use of -E. It's not needed in our build because we use ?= for
    the respective variables, which means that we'll take the environment
    value (if any) anyway.
3.  Properly declare phony targets as phony as bmake is a lot smarter (and
    thus agressive) about build avoidance.
4.  Make sure CLEANFILES is complete and use it on .NOPATH. bmake is a lot
    smarter about build avoidance and should not find files we generate in
    the source tree. We should not have files in the repository we want to
    generate, but this is an easier way to cross this hurdle.
5.  Have behavior under bmake the same as it is under make with respect to
    halting when sub-commands fail. Add "set -e" to compound commands so
    that bmake is informed when sub-commands fail.
6.  Make sure crunchgen uses the same make as the rest of the build. This
    is important when the make utility isn't called make (but bmake for
    example).
7.  While here, add support for using MAKEOBJDIR to set the object tree
    location. It's the second alternative bmake looks for when determining
    the actual object directory (= .OBJDIR).

61fcb6bec9 A workaround in r238563 was for makes (notably bmake) without the
internal knowledge that "cd" is a shell's built-in.  Such makes
may attempt to exec() "cd" that in turn will fail on systems that
lack the "cd" executable.

4da573d910 Merging of projects/armv6, part 3
r238211:
Support TARGET_ARCH=armv6 and TARGET_ARCH=armv6eb

This adds a new TARGET_ARCH for building on ARM
processors that support the ARMv6K multiprocessor
extensions.  In particular, these processors have
better support for TLS and mutex operations.

This mostly touches a lot of Makefiles to extend
existing patterns for inferring CPUARCH from ARCH.
It also configures:
 * GCC to default to arm1176jz-s
 * GCC to predefine __FreeBSD_ARCH_armv6__
 * gas to default to ARM_ARCH_V6K
 * uname -p to return 'armv6'
 * make so that MACHINE_ARCH defaults to 'armv6'
It also changes a number of headers to use
the compiler __ARM_ARCH_XXX__ macros to configure
processor-specific support routines.
