sh: gcc4 support.
This fixes up the kernel for gcc4. The existing exception handlers needed some wrapping for pt_regs access, acessing the registers via a RELOC_HIDE() pointer. The strcpy() issues popped up here too, so add -ffreestanding and kill off the symbol export. Signed-off-by: Stuart Menefy <stuart.menefy@st.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
