build: don't -L/usr/pkg/lib

You might have to update the compiler-rt package! See UPDATING.

	. the purpose of this -L was solely to find compiler-rt, which contains
	  runtime support code for clang-compiled binaries
	. this also makes all other packaged libraries visible, however
	. it is cleaner to isolate the base system from packages, and so
	  compiler-rt puts itself in /usr/pkg/compiler-rt/lib/ too, which the
	  base system henceforth uses exclusively
	. e.g. this solves a link failure when libfetch is installed as a
	  package
	. the new compiler-rt package also puts itself in /usr/pkg/lib for 'old'
	  systems; that is harmless. The benefit of 'new' systems is that the other
	  packages are hidden.
