gcc 4.8: sync patches with OE-core

This brings us inline with OE-core gcc and replaces the backported sysroot patch with the upstream one.

Only 0036-PR-target-56102.patch didn't apply and was left out of the SRC_URI

+Fix PR56797
+http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56797
+
+The problem is that peephole optimizer thinks it can generate an ldm, but
+the pattern for ldm no longer matches, because after r188738 it requires
+that if one of the destination registers is SP then the base register must
+be SP, and it's not SP in the test case. 
+
+The test case fails on armv5t but doesn't fail on armv6t2 or armv7-a because
+peephole doesn't trigger there (because there is a different epilogue
+sequence). It looks like a latent problem for other architecture or CPUs.
+
+This patch adds this condition to the peephole optimizer.
+
+No regression on qemu for arm-none-eabi and fixes the test reported in the
+PR. I couldn't minimize the test sufficiently to include it in the
+testsuite. 
+
+Ok for trunk?
+
+Thanks,

+When cross compiling a target gcc, target flags may be used on the host
+
+Configure identifies a number of warning flags (WARN_CFLAGS and
+WARN_CXXFLAGS) from the $CC value.  The cross compiler may be different
+from the host compiler and may not support the same set of flags.  This
+leads to problems such as:
+
+cc1plus: error: unrecognized command line option "-Wno-narrowing"
+cc1plus: error: unrecognized command line option "-Wno-overlength-strings"
+
+Work around this problem by removing the warning flags from the
+BUILD_CXXFLAGS value, in a way similar to the BUILD_CFLAGS.

+
+Note this is a *build* target (in build-x86_64-linux) so it should be using 
+the host "gcc", not x86_64-pokysdk-mingw32-gcc. Since the mingw32 headers are 
+very different, using the wrong cpp is a real problem. It is leaking into 
+configure through the CPP variable. Ultimately this leads to build failures 
+related to not being able to include a process.h file for pem-unix.c.
+
+The fix is to ensure we export a sane CPP value into the build environment when
+using build targets. We could define a CPP_FOR_BUILD value which may be the version
+which needs to be upstreamed but for now, this fix is good enough to avoid the 
+problem.

+gengtype is generated for both the build system and the target. -DGENERATOR_FILE
+was added in the patch http://gcc.gnu.org/ml/gcc-patches/2012-07/msg00273.html
+and was applied to both versions of gengtype.
+
+Unfortunately the presence of this flag triggers the build configuration (bconfig.h) 
+to be included for the target build of gengtype. Compiling gengtype with the target 
+compiler and bconfig.h can result in errors if the build and target systems are 
+dissimilar. An example case this fails is cross compiling gcc on linux for a darwin 
+target system:
+
+In file included from /media/build1/poky/build/tmp/work-shared/gcc-4.8.1-r0/gcc-4.8.1/gcc/gengtype-parse.c:25:0:

+|  #  define fputc(C, Stream) fputc_unlocked (C, Stream)
+
+which occurs since auto-build.h and auto-host.h have differnet values of
+HAVE_FPUTC_UNLOCKED:
+
+#define HAVE_FPUTC_UNLOCKED 1
+/* #undef HAVE_FPUTS_UNLOCKED */
+
+The obvious fix is to only include the flag on build/ targets which this patch does, however 
+this also leads to compile errors due to const_tree being undefined but used in double_int.h
+
+I added a GENERATOR_FILE2 flag to workaround those in the 
+target case and allow the build to succeed.
+
+Only the build/gengtypes should have the -DGENERATOR_FILE
