mk: fix link of combined shared library using CC

Browse Source 
If we set EXTRA_CFLAGS=-O0, build fails with following error:
	/usr/bin/ld: test: hidden symbol `mknod' in /usr/lib64/libc_nonshared.a(mknod.oS) is referenced by DSO

Fix: link combined shared lib using CC if LINK_USING_CC is enabled.
