License: LIBPNG
Libpng was written as a companion to the PNG specification, as a
way to reduce the amount of time and effort it takes to support
the PNG file format in application programs.  Most users will not
have to modify the library significantly; advanced users may want
to modify it more.  The library was coded for both users.  All
attempts were made to make it as complete as possible, while
keeping the code easy to understand.  Currently, this library
only supports C.  Support for other languages is being considered.

- Autodetect the installed linux_base port and use LINUX_DEFAULT only as
  a last resort.
- Construct a list of DISTFILES for every architecture (amd64, i386).
  Select one list for regular make and all lists for make makesum so linux
  ports can have one combined distinfo file.
- Set DIST_SUBDIR?=centos so there's only one copy of common distfiles.
- Use MASTER_SITES and DISTFILES groups so make fetch is a bit smarter.
- Regenerate all distinfo files.
- For linux_base-c6 (just like linux_base-c7 already does) turn bin, lib,
  lib64 and sbin into symbolic links to the same directory under usr.
  This fixes the problem where some programs/libraries exist under / on
  FreeBSD and /usr on Linux or vice versa and then depending on the order
  of search paths Linux programs may run/load FreeBSD programs/libraries
  and fail.
- Turn usr/share/icons into a symbolic link to LOCALBASE/share/icons so

Update Linux CentOS 7 ports to 7.3.1611.  While 7.2 had semi-official i386
packages there are no such packages for 7.3 yet so i386 support has been
marked IGNORE for now.

Change DIST_SUBDIR to just "centos" so distfiles that remain the same
between major versions don't have to be redownloaded.

Remove fmake hacks from

Add Linux CentOS 7 infrastructure ports.

Mk/Uses/ changes:
- Add support for architecture neutral (noarch) distfiles.
- Add support for 64-bit only ports: set IGNORE on i386 and don't install
  32-bit compat libraries on amd64.
