Revert "Fix (another) linker library order"

This reverts commit a51ac6d9a011ba10b0be396dc1e801b2fc829651.

Hrm, actually, these patches are wrong.

commit 725e63c5194bfdcde0a2a3507aca156ba36cf49f for instance:

"Libraries must be specified after the binary target."

 demo: demo.o
-       $(CC) -o $@ $(LIBS) $^
+       $(CC) -o $@ $^ $(LIBS)

the binary target here is "$@".

$^ is the source file name (demo.c).

this patch moves the source file name prior to the libraries, which is
incorrect (ref: gcc(1)). The input files should appear last.

So it breaks builds where $(LIBS) is non-empty.
