Subject: [PATCH v2 3/7] selftests/nolibc: libc-test: use HOSTCC instead of CC

libc-test is mainly added to compare the behavior of nolibc to the
system libc, it is meaningless and error-prone with cross compiling.

Let's use HOSTCC instead of CC to avoid wrongly use cross compiler when
CROSS_COMPILE is passed or customized.
