Unfortunately make is whitespace sensitive, so you can't indent here
without getting a syntax error in the case that dpdk is not installed.
Instead of the error message you get e.g.:

	Makefile:12: *** recipe commences before first target.  Stop.

This applies to all makefiles in this patch, I think.
