Synchronize on NetBSD-CVS (2013/12/1 12:00:00 UTC)

- Fix for possible unset uid/gid in toproto
- Fix for default mtree style
- Update libelf
- Importing libexecinfo
- Resynchronize GCC, mpc, gmp, mpfr
- build.sh: Replace params with show-params.
This has been done as the make target has been renamed in the same
way, while a new target named params has been added. This new
target generates a file containing all the parameters, instead of
printing it on the console.
- Update test48 with new etc/services (Fix by Ben Gras <ben@minix3.org)
get getservbyport() out of the inner loop

Remove obsolete compatibility links

* /usr/bin/strip would be replaced by a link, even when compiling

* Updated minix-spec.h to use the correct dynamic linker, and removed
the previously used symlinks.

Adding missing symlink to dynamic loader.

As the release script does not copy over files from the currently
running system anymore, it has appeared that some binaries are
looking for the dynamic loader in /lib instead of /usr/lib.

It has been replaced by a symlink to ensure compatibility with
binaries, until the path is updated in all the toolchains to be
the same.

Upgrading build system to new NetBSD revision

The tested targets are the followgin ones:
* tools
* distribution
* sets
* release

The remaining NetBSD targets have not been disabled nor tested
*at all*. Try them at your own risk, they may reboot the earth.

For all compliant Makefiles, objects and generated files are put in
MAKEOBJDIR, which means you can now keep objects between two branch
switching. Same for DESTDIR, please refer to build.sh options.

Regarding new or modifications of Makefiles a few things:
* Read share/mk/bsd.README
* If you add a subdirectory, add a Makefile in it, and have it called
by the parent through the SUBDIR variable.
* Do not add arbitrary inclusion which crosses to another branch of
the hierarchy; If you can't do without it, put a comment on why.
If possible, do not use inclusion at all.
* Use as much as possible the infrastructure, it is here to make
life easier, do not fight it.

Sets and package are now used to track files.
We have one set called "minix", composed of one package called "minix-sys"

build shared versions of libraries

building defaults to off until clang is updated.

current clang does not handle -shared, necessary to change the ld
invocation to build shared libraries properly.

build shared versions of libraries

building defaults to off until clang is updated.

current clang does not handle -shared, necessary to change the ld
invocation to build shared libraries properly. a new clang should be
installed and MKPIC defaults to no unless the newer clang is detected.

changes:

. mainly small imports of a Makefile or two and small fixes
(turning things back on that were turned off in Makefiles)
. e.g.: dynamic librefuse now depends on dynamic
libpuffs, so libpuffs has to be built dynamically too
and a make dependency barrier is needed in lib/Makefile
. all library objects now have a PIC (for .so) and non-PIC
version, so everything is built twice.
. generate PIC versions of the compat (un-RENAMEd) jump files,
include function type annotation in generated assembly
. build progs with -static by default for now
. also build ld.elf_so
. also import NetBSD ldd
