Merge remote-tracking branch 'qatar/master'
* qatar/master: build: remove empty $(OBJS) target build: make rule for linking ff* apply only to these targets build: rearrange some lines in a more logical way s302m: fix resampling for 16 and 24bits. ARM: remove MUL64 and MAC64 inline asm build: clean up .PHONY lists build: move all (un)install* target aliases to toplevel Makefile flvenc: propagate error properly build: remove stale dependency build: do not add CFLAGS-yes to CFLAGS utils.c: fix crash with threading enabled. configure: simplify source_path setup configure: remove --source-path option lavf: deprecate AVFormatParameters.time_base. img2: add framerate private option. img2: add video_size private option. img2: add pixel_format private option. tty: add framerate private option. Conflicts: Makefile configure Merged-by: Michael Niedermayer <michaelni@gmx.at>
