[Cin] More adventures in (emulated) ppc64le land

[Andrew Randrianasulu]

Sorry for a bit of "dev" spam, just trying to be useful for some (Daniel).

After if 0'ing most of code in 
https://git.cinelerra-gg.org/git/?p=goodguy/cinelerra.git;a=blob;f=cinelerra-5.1/guicast/bcsignals.C;h=ed50cfb15d9e8ac38c630c3096c9ab2b77fce477;hb=HEAD

handle_dump()  (so it will compile into something even on ppc)

and shuting up "BOOTSTRAP undeclared" in 
https://git.cinelerra-gg.org/git/?p=goodguy/cinelerra.git;a=blob;f=cinelerra-5.1/guicast/bootstrap.c;h=a697492be44f9566ba7be05b5a32766dce787725;hb=HEAD

see line 197,  sprintf(system_command, "%s %s %s", BOOTSTRAP, temp_path, 
out_path); 

my system somewhat dislikes it.

I got into futher trouble :/

fileac3 uses filempeg and filempeg gives  incomplete class FileMPEG if you try 
to compile Cin-gg with --with-commercials=no, with-libzmpeg3=no :/
