libselinux: use correct definition of ARCH
The Makefile of libselinux performs the following check:
ARCH := $(patsubst i%86,i386,$(shell uname -m))
ifneq (,$(filter i386,$(ARCH)))
TLSFLAGS += -mno-tls-direct-seg-refs
endif
Which means that if the host machine is an x86, then TLSFLAGS will
contain -mno-tls-direct-seg-refs. That command line option causes
libselinux to fail when building it for target architectures where the
compiler doesn't support that option, i.e. MIPS:
mips-img-linux-gnu-gcc: error: unrecognized command line option
‘-mno-tls-direct-seg-refs’
So to fix that problem we can set the ARCH variable to $(KERNEL_ARCH),
and then append it to the LIBSELINUX_MAKE_OPTS.
