PATCH: Resolve (another set of) non-portable use of $<

[Loren James Rittle]

As tested (with both GNU make and BSD make) on i386-*-freebsd[45] and
applied.  Funny how these things come in batches (the b-i-b merge
brought in similar idiomatic usage of $<)...

	* src/Makefile.am: Resolve non-portable use of $<.
	* src/Makefile.in: Rebuilt.
