Because Andrea had a compile problem and Andrew found an update to mjpegtools from 2.1.0 to 2.2.1 that seemed to solve the problem, I have been testing this.
Questions for Andrew concerning the patches in 2.1.0 to be moved to 2.2.1:
??? patch 1,2,3 are no longer relevant because patch1 cpuinfo.sh file no longer exists; patch2 NOPIC not there; patch3 bad spelling must be gone (wink, wink).
??? patch 4,5,6,7 appear to be needed for TERMUX. Is that still necessary? and bthread.h needs to be created as in patch7?
