linux: Ensure we have buildable kernel recipes for each machine

Fix various kernels to build with our toolchain, this includes well known fixes
for:
* sumversion.c: compilation failing with a 'PATH_MAX' undeclared (fixed by
    adding limits.h to sumversions includes
* a patch taken from oe.dev to stop GCC >= 4.3 from optimizing a loop which
    causes compilation to fail
* Fixing the KERNEL_OUTPUT for mx31 and nokia800 kernel recipes

+Subject: [PATCH] fix-gcc-4.3-false-modulo-optimization.patch
+
+I tried to compile the current stable kernel
+(a2ef813d2f439a3e9f377d33a2e5baad098afb7e)
+and get the following errors:
+
+kernel/built-in.o: In function `timespec_add_ns':
+/mnt/data/Freerunner/Gentoo/rootinstall/usr/src/linux/include/linux/time.h:174:
+undefined reference to `__aeabi_uldivmod'
+/mnt/data/Freerunner/Gentoo/rootinstall/usr/src/linux/include/linux/time.h:179:

+/mnt/data/Freerunner/Gentoo/rootinstall/usr/src/linux/include/linux/time.h:179:
+undefined reference to `__aeabi_uldivmod'
+
+applying the following patch solved the problem:
+--------
+Prevent gcc-4.3 form "optimizing" the while loop into a costly modulo operation.
+Patch found at http://lkml.org/lkml/2008/2/22/464.
