targets/pipe-loader: Convert to automake

C++ linking (controlled by the nodist_EXTRA idiom) is needed

unconditionally for:
	nouveau (uses C++ in the driver)
	r300 (since LLVM is always required)
	radeonsi (since LLVM is always required)
	swrast (if builting LLVM pipe)

and conditionally (depends whether LLVM is enabled) for
	i915
	r600
	vmwgfx

and never needed for swrast (softpipe).

Unfortunately, automake seems to *always* link with C++ if nodist_EXTRA
is specified, even inside a false conditional. Not sure if this is a
bug, but it does seem to be weird behavior.

    - Fix some undefined symbols.
