Ross Burton 4574919d30 scripts/makefile-getvar: add script to get values from Makefiles
There is often a need to extract a value from a Makefile, and standard
GNU Make doesn't provide a way to do this.  This script lets you access
values from Makefiles directly:

$ makefile-getvar curl/tests/server/Makefile noinst_PROGRAMS
getpart resolve rtspd sockfilt sws tftpd fake_ntlm socksd disabled mqttd
