[PATCH] gnu: util-macros: Install .pc file in lib/pkgconfig; remove INSTALL file.

[Mark H Weaver]

This patch fixes 'util-macros' to install its *.pc file in
PREFIX/lib/pkgconfig instead of PREFIX/share/pkgconfig, and to avoid
installing its (standard generic) INSTALL file into
PREFIX/share/util-macros/INSTALL.

Subject: [PATCH] gnu: util-macros: Install .pc file in lib/pkgconfig;
 remove INSTALL file.

* gnu/packages/xorg.scm (util-macros): Substitute "$(libdir)/pkgconfig"
  for "$(datadir)/pkgconfig" in Makefile.in.  After install, remove
  share/util-macros/INSTALL and share/util-macros.
