Provide pkg-config (.pc) scripts This allows a project to use PKG_CHECK_MODULES() in its configure.ac file to easily check for the presence of libjpeg-turbo and modify the compiler/linker flags accordingly. Note that if a project relies solely on pkg-config to check for libjpeg-turbo, then it will not be possible to build that project using libjpeg or an earlier version of libjpeg-turbo. Closes #53 Based on: https://github.com/cberner/libjpeg-turbo/commit/496713871939b550d00005b4042420da41641a0a
