Merge branch 'gcc_syslibs'

* From now on, the gcc-specific system libraries (libgcc, libsupc++ and
libstdc++) are provided by separate packages built along with gcc:
- gcc_syslibs contains the shared libraries (libgcc_s.so, libsupc++.so and
libstdc++.so)
- gcc_syslibs_devel contains the static libraries and both c++ and gcc
headers
The shared libraries now make proper use of symbol versioning and there
are version-specific symlinks
* The buildsystem has been adjusted to no longer use the libraries and
headers from the cross-compiler, but use the ones provided by the
above-mentioned packages. The only exception is that the 32-bit libraries
required for the bootloader of the x86_64 architecture are still taken
from the cross-compiler.

Use libstdc++, libsupc++ and libgcc from gcc_syslibs.

* Instead of faking libstdc++.so from libstdc++.a, use libstdc++.so
from the gcc_syslibs build feature for everything except x86_gcc2.
* Use libgcc_s.so from the gcc_syslibs build feature for everything but
x86_gcc2 (which still carries libgcc as part of libroot.so).
* Drop filtering of libgcc objects for libroot, as that is no longer
necessary since we're only using libgcc-as-single-object for libroot
with x86_gcc2, where the filtered object file doesn't exist. Should
the objects that used to be filtered cause any problems as part of
libgcc_s.so, we can always filter them as part of the gcc build.
* Use libsupc++.so from the gcc_syslibs build feature for everything but
x86_gcc2.
* Adjust all Jamfiles accordingly.
* Deactivate building of faked libstdc++.so for non-x86-gcc2. For
x86_gcc2, we still build libstdc++.so from the sources in the Haiku
source tree as part of the Haiku build .
* Put gcc_syslibs package onto the image, when needed.

Patch by Christof Lutteroth:
* copyright headers for the files of the libraries linprog and alm
* new class Summand for representing summands in a linear constraint
* merged class SoftConstraint into class Constraint; Constraint now
supports both soft and hard constraint functionality
* new AddConstraint methods in class LinearSpec for directly setting
constraints with 1 to 4 summands
* code cleanups by using aforementioned AddConstraint methods
* a new very simple test application for alm
* some style corrections

Added libalm.so and its dependency liblinprog.so. libalm.so provides a
BLayout implementation (BALMLayout) using the Auckland Layout Model
(ALM). The original ALM was implemented by Christof Lutteroth, the
Haiku/C++ version by James Kim.
The code needs some review, but the test programs seem to work fine.
