linux-qoriq-sdk(-headers): upgrade to the version of sdk-1.4
1.Update kernel version to 3.8.
2.add DEPENDS libgcc and append TOOLCHAIN_OPTIONS to KERNEL_{CC,LD}.
kernel in sdk 1.4 need run-time support libraries 'libgcc.a', added
in file arch/powerpc/Makefile:
LIBGCC := $(shell $(CC) $(KBUILD_CFLAGS) -print-libgcc-file-name)
Without passing the TOOLCHAIN_OPTIONS (define --sysroot parameter),
it will fail to find the libgcc.a.
3.Also remove the patches which were already merged on git tree.
