[PATCH 1/1] Update gnu make completion for version 4.4

[Shohei YOSHIDA <syohex@xxxxxxxxx>]

Add `-b,-m`, `--jobserver-style`, `--shuffle` and `--trace` options
And delete '--warn-undefined-functions' option. This option was implemented
only in redhat's older make and the official gnu make has never supported it.
