microblaze: Pass -m{big,little}-endian through KBUILD_CPPFLAGS
These parameters are also necessary for preprocessed files which do not
contain code. One example is arch/microblaze/kernel/vmlinux.lds.S which
inspects __MICROBLAZEEL__ for the definition of 'jiffies_64'.
As currently the endianness is not passed from the build system for this
file, the preprocessor will instead use the default endianness of the
toolchain. When a default big-endian toolchain is used to build a
little-endian kernel, that kernel will hang during delay calibration
as 'jiffies' never changes.
Make sure all preprocessor invocations know about the correct endianness
by passing it through KBUILD_CPPFLAGS. This will also be inherited by
CFLAGS and AFLAGS.
