>Description:
	fontenc.pc pkgconfig file installed in NetBSD-current (-11 and -10 are
	not affected) has incorrect Requires.private, generated
	/usr/X11R7/lib/pkgconfig/fontenc.pc is:
	
	   ...
	     6  Name: fontenc
	     7  Description: The fontenc Library
	     8  URL: https://gitlab.freedesktop.org/xorg/lib/libfontenc/
	     9  Version: 1.1.9
	    10  Requires.private: -lz
	    11  Libs: -Wl,-rpath,${libdir} -L${libdir} -lfontenc
	   ...
	
	The Requires.private is incorrect and it should be "zlib" instead of
	"-lz" (we need to specify packages there).
>How-To-Repeat:
	Code inspection in generated /usr/X11R7/lib/pkgconfig/fontenc.pc.
	Also checks src/external/mit/xorg/lib/libfontenc/Makefile:
	
	   ...
	    22  PKGCONFIG_SED_FLAGS= \
	    23          -e "s,@Z_REQUIRES@,-lz,"
	   ...

	And also:

	 $ pkg-config --libs fontenc
	 Package -lz was not found in the pkg-config search path.
	 Perhaps you should add the directory containing `-lz.pc'
	 to the PKG_CONFIG_PATH environment variable
	 Package '-lz', required by 'fontenc', not found

>Fix:
	In src/external/mit/xorg/lib/libfontenc/Makefile we need to change the
	@Z_REQUIRES@ to zlib (instead of -lz).
