[Diego Elio Pettenò]

libbluray | branch: flameeyes | Diego Elio Pettenò <flameeyes at flameeyes.eu> | Thu Feb 14 17:57:35 2013 -0800| [57c02f037d412f6fa872e137be001e0027223c00] | committer: Diego Elio Pettenò

build: cleanup pkg-config checks.

Avoid trying being a smartass when pkg-config is not found, it's rare
enough that it shouldn't really matter.
