   GNU Make 4.x

 - Some minor fixes for coccinelle patches

 - Do not overwrite .gitignore in the output directory in case it is
   version-controlled

 - Fix missed record-mcount bug for dynamic ftrace

 - Fix endianness bug in modversions for relative CRC

 - Cater to '^H' key code in Kconfig ncurses programs
