Revision 341119

- Fix the build on 10 and beyond.
  Since r253839 ld(1) behaves more strictly and does not pull in indirect
  shared library dependencies (in this case, libX11.so). Upstream correctly
  has -lX11 in the linker line, but r315151 removed this section in
  patch-src_Makefile.
  Based on a patch by Jan Henrik Sylvester <me@janh.de> in [1].

- While here, convert USE_GMAKE=yes to USES=gmake.
