Check for PKG_CONFIG_LIBDIR when cross compiling. 

When cross-compiling, check for PKG_CONFIG_LIBDIR instead of
PKG_CONFIG_PATH. pkg-config searches for pc files in PKG_CONFIG_PATH
*and* the compiled in defaults (/usr/lib/pkgconfig). This means that
pc files from the host get found when cross-compiling.

Setting PKG_CONFIG_LIBDIR makes pkg-config search only in the path
set in PKG_CONFIG_LIBDIR.
