ARC: MWDT: link mwdt libc only if it is required

Browse source 
We don't need MWDT libc if we are using minimal one provided by
Zephyr. So let's avoid linking mwdt libc if CONFIG_MINIMAL_LIBC
is enabled.

# There are two options:
# - We have full MWDT libc support and we link MWDT libc - this is default
# behavior and we don't need to do something for that.
# - We use minimal libc provided by Zephyr itself. In that case we must not
# link MWDT libc, but we still need to link libmw

# Funny thing is if this is set to =error, some architectures will
# skip this flag even though the compiler flag check passes
# (e.g. ARC and Xtensa). So warning should be the default for now.
