sh: Merge the split arch/sh/boot/compressed/ Makefiles. This kills off the _64 variant and moves the _32 one over as the generic one to use. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

sh: Enable CONFIG_GCOV_PROFILE_ALL for sh 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.

sh: Decouple mcount from ftrace. 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.

sh: Remove compressed kernel libgcc dependency. 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.
