pkg-config file looks invalid; contains @OPENCL_LIB@ after installation #241

It looks like the installed pkg-config file still has a macro in it, instead of the flags for the OpenCL libs.

$ pkg-config --libs tesseract --static
-L/usr/local/Cellar/tesseract/3.04.01/lib -L/usr/local/Cellar/leptonica/1.72/lib 
  -ltesseract -lpthread -llept @OPENCL_LIB@ -llept -lz -lpng -ljpeg -ltiff

Looks like this is because tesseract.pc.in uses @OPENCL_LIB@, but that's not defined by config.status. OPENCL_LDFLAGS is defined; should it be using that instead? If I modify tesseract.pc.in to use @OPENCL_LDFLAGS@, I get normal-looking link flags in the result. (This is on OS X 10.9.5.)

$ pkg-config --libs tesseract --static
-L/usr/local/Cellar/tesseract/3.04.01/lib -L/usr/local/Cellar/leptonica/1.72/lib -ltesseract -lpthread -llept -framework OpenCL -llept -lz -lpng -ljpeg -ltiff

Also, the -llept flag is duplicated in the output. Looks like this is because -llept is in Libs.private in addition to being in Requires.private. Is the Libs.private -llept redundant?

Requires.private: lept
Libs: -L${libdir} -ltesseract
Libs.private: -lpthread -llept @OPENCL_LIB@

This was noticed by a Mac Homebrew user: Homebrew/legacy-homebrew#49579.
