System: NetBSD optiplex 9.3 NetBSD 9.3 (GENERIC) #0: Thu Aug  4 15:30:37 UTC 2022  mkrepro%mkrepro.NetBSD.org@localhost:/usr/src/sys/arch/i386/compile/GENERIC i386
Architecture: i386
Machine: i386
>Description:
NetBSD 9.3 has:
 - freetype2 2.10.4 and /usr/X11R7/lib/libfreetype.so.19.0
 - fontconfig 2.13.1 and /usr/X11R7/lib/libfontconfig.so.2.3

pkgsrc-2023Q2 has:
 - freetype2 2.13.0 in pkgsrc/graphics/freetype2/Makefile
   and BUILDLINK_API_DEPENDS in buildlink3.mk is also 2.13.0
  https://github.com/NetBSD/pkgsrc/commit/5c74c638
 - fontconfig 2.14.2 in pkgsrc/fonts/fontconfig/Makefile
   and also requires freetypes>=2.13.0 via buildlink3.mk,
   but BUILDLINK_API_DEPENDS in buildlink3.mk is 2.11.91
  https://github.com/NetBSD/pkgsrc/blob/da7caf4f/fonts/fontconfig/buildlink3.mk#L8

This causes mungled libfreetype2 dependencies, for example,
libcairo.so installed from pkgsrc/graphics/cairo requires:

This causes broken rendering of emoji on cairo applications,
at least binaries that pull ruby-cairo:

Bump BUILDLINK_API_DEPENDS in fontconfig/buildlink3.mk to pull
proper pkgsrc version fontconfig for NetBSD 9.3?
(not sure it's acceptable in the release branch)
