  build: Generate better pkg-config files for static-only builds
  
  pkg-config supports `Requires.private` and `Libs.private` fields for
  static linking. However, if you're building a dynamic binary, then
  pkg-config will use the non-private fields, even if just the static
  libxml2 is available. This will result in libxml2 being underlinked,
  causing the build to fail. The solution is to fold the private fields
  into the non-private fields when the shared libxml2 is not being built.
  
  This works for Autotools and CMake. Meson also knows how to handle this
  when it automatically generates pkg-config files.

                          add --dynamic to print only shared libraries
    --cflags		print pre-processor and compiler flags
    --modules		module support enabled
    --help		display this help and exit
    --version		output version information
