Add gcc patch for multiarch support. 

On Debian-based distributions,  gcc FTBFS because of special  linker files and
architecture-dependent  headers being  available in  /usr/lib/<triplet> rather
than /usr/lib  and /usr/lib64. This avoids  settings respectively LIBRARY_PATH
and CPATH manually on such distributions.

# DP: Add multiarch support to GCC.
# DP:
# DP: Convert the multilib option to a target triplet,
# DP: add multiarch include directories and libraries path:
# DP: /usr/local/include/<arch>-linux-gnu
# DP: /usr/include/<arch>-linux-gnu
# DP: /usr/lib/<arch>-linux-gnu
# DP: to the system paths.
# DP:
# DP: Original patch:
# DP: http://anonscm.debian.org/viewvc/gcccvs/branches/sid/gcc-4.5/debian/patches/gcc-multiarch.diff?revision=5086&view=co
2011-08-05 Arnaud Fontaine <arnaud.fontaine@nexedi.com>
* Enable multiarch unconditionally.
2011-03-08 Steve Langasek <steve.langasek@linaro.org>
* Canonicalize x86 to i386 everywhere, not i486/i686
2009-03-24 Arthur Loiret <aloiret@debian.org>
* configure.ac: Handle --enable-multiarch and --with-multiarch-defaults.
* config.gcc: Define MULTIARCH_DEFAULTS if multiarch is enabled.
* config.in [!USED_FOR_TARGET]: Undef ENABLE_MULTIARCH.
* gcc.c: include multiarch.h.
(set_multiarch_dir): New function. Adds the multiarch directories to
the library path.
[ENABLE_MULTIARCH]: Use it.
* cppdefault.c [LOCAL_INCLUDE_DIR, STANDARD_INCLUDE_DIR] Add an include
directory for multiarch directories.
* incpath.c: include multiarch.h
[ENABLE_MULTIARCH]: Add the multiarch directory to include directories.
* Makefile.in (MULTIARCH_H): New. Use it for incpath.o and gcc.o.
* multiarch.h: New file.
