gentoo-overlay/dev-cpp/sparsehash/files/sparsehash-2.0.3-fix-buildsystem.patch

* Do not override $(docdir) as part of the GNU conventions
* Do not install 'COPYING' and 'INSTALL'
* Install html files using html_ prefix and not doc_ prefix
* Do not try to link against tcmalloc, the complexity of juggling
  the options around isn't worth it
