SH-2A is unable to combine the kernel and libgcc objects due to
fundamental disagreements over FDPIC settings. As the kernel already
contains all of the libgcc bits broken out, there's not much need to
bother with the linking anymore, as everything can already be derived
from the lib dir.

This simply plugs in the necessary bits to ensure that everything is
built uniformly, enabling us to wean the compressed build off of explicit
libgcc linking.

This patch enables gcov kernel profiling over the whole kernel for sh.
Profiling of specific files individually already worked. A handful of
files have to be explicitly excluded from the profiling to avoid
breaking things, notably pmb.c.

We can't necessarily use the P1SEG region to access RAM when running in
32BIT mode, so use CONFIG_MEMORY_START as the base address.

The VBR value needs to be initialized in order for any of the bios
trapping to work, and as we don't do that until slightly later in the
boot process, this has no real chance of working.

The only reason for using this in the past was due to the fact that early
serial initialization wasn't possible, but now that early sh-sci is
supported by everyone, there's no longer any reason to support the
sh_bios hacks in the first place. Given that, we just kill off the
references completely.

This adds a general CONFIG_MCOUNT in order to permit mcount generation
without ftrace support. This is primarily for allowing platforms to
enable aggressive stack overflow checking without having to enable ftrace
support. Based on the sparc64 implementation.

The variable CFLAGS is a wellknown variable and the usage by
kbuild may result in unexpected behaviour.
On top of that several people over time has asked for a way to
pass in additional flags to gcc.

This patch replace use of CFLAGS with KBUILD_CFLAGS all over the
tree and enabling one to use:
make CFLAGS=...
to specify additional gcc commandline options.

One usecase is when trying to find gcc bugs but other
use cases has been requested too.

Patch was tested on following architectures:
alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k

Test was simple to do a defconfig build, apply the patch and check
that nothing got rebuild.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
