Now when a lib is marked as PRIVATELIB it is renamed into libprivate$foo instead
of being installed in /usr/lib/private and playing with rpath.
Also allow to install headers for PRIVATELIBS in that case the headers will be
installed in /usr/include/private/$foo
Keep the headers under a private namespace to prevent third party build system
to easily find them to ensure they are only used on purpose.
This allows for non base applications to statically link against a library in
base which is linked to a privatelib
Treating PRIVATELIBS as regular libraries allows to push them into our current
compatX packages if needed.

This fixes C++ libraries not implicitly linking in libc++. This is
generally not an issue because the final linking with the compiled binary
will involve CXX via PROG_CXX or other means. It is however
inconsistent with libraries implicitly linking in libc and problematic
for trying to build libraries with '-z defs' to ensure all direct
dependencies are linked in.
libatf-c++ is currently the only consumer of this new feature.

To mark a library as private, define PRIVATELIB in its Makefile. It
will be installed in LIBPRIVATEDIR, which is normally /usr/lib/private
(or /usr/lib32/private for 32-bit libraries on 64-bit platforms).
To indicate that a program or library depends on a private library,
define USEPRIVATELIB in its Makefile. The correct version of
LIBPRIVATEDIR will be added to its run-time library search path.

is automatically applied when WITH_DEBUG_FILES is set.
The debug files are now named ${prog}.debug and ${shlib}.debug for
consistency with other systems and documentation. In addition they are
installed under /usr/lib/debug, to simplify the process of installing
them if needed after a crash. Users of bsd.{prog,lib}.mk outside of the
base system place the standalone debug files in a .debug subdirectory.
GDB automatically searches both of these directories for standalone
