toolchain: remove references to $(LIBC)/utils subtarget

The utils subtarget was used for uClibc and eglibc
which are both obsolete and replaced in Openwrt by mainline
musl and glibc, which do not have a utils Makefile target.

Ref: 5d19a38d8 ("toolchain: sync eglibc headers/build split with uclibc changes")
Fixes: 63fb17520 ("toolchain: remove uClibc-ng")
