pkgs/development/libraries/glibc/darwin-cross-build.patch

   1 enable cross-compilation of glibc on Darwin (build=Darwin, host=Linux)
   2 * increase ulimit for open files: macOS default of 256 is too low for glibc build system
   3 * use host version of ar, which is given by environment variable
   4 * build system uses stamp.os and stamp.oS files, which only differ in case;
   5   this fails on macOS, so replace .oS with .o_S
