media-libs/libsfml: build and install pkgconfig on mingw-w64

This is an upstream commit, which will be in the 2.5.0 release, which
allows creation of the sfml pkgconfig files on mingw-w64 when either
SFML_INSTALL_PKGCONFIG_FILES is true or if their internal check
SFML_OS_SUPPORTS_PKGCONFIG returns true; since we explicitly set the
former this change will allow build and install of sfml pc files on
mingw-w64 and (I think) osx targets.

Closes: https://github.com/gentoo/gentoo/pull/7518
Package-Manager: Portage-2.3.24, Repoman-2.3.6

+commit 5fe5e5d6d7792e37685a437551ffa8ed5161fcc1
+Author: Rafael Kitover <rkitover@gmail.com>

+
+    packaging support improvements
+
+    This grew out of my work creating an sfml port for macports, but should
+    be helpful for package maintainers of various distributions:
+
+    * add an SFML_USE_SYSTEM_DEPS option to ignore everything in extlibs/
+      except for headers/stb_image, and use the system versions
+
+    * install pkg-config files if a pkg-config program is found
+      and either lib/pkgconfig or libdata/pkgconfig exists under the
+      INSTALL_PREFIX, or the SFML_INSTALL_PKGCONFIG_FILES flag is set
+      explicitly
+
+    * install pkg-config files for static libs too, add the necessary
+      Requires.private and Libs.private entries to the .pc files to support
+      static linking
+
+    * on OS X, honor all INSTALL_NAME and RPATH related cmake variables and
+      only set the INSTALL_NAME_DIR to "@rpath" if none of them is set, this
+      preserves the default behavior of using @rpath but also allows
+      overriding by the usual cmake mechanisms
