Comment (by awilfox):

 This patch has been tested by me in the following environments:

 (All environments running Adélie Linux, kernel 4.14.48-mc8-easy, musl libc
 1.1.19, GCC 6.4.0)

 * 32-bit PowerPC 7447 "G4" (Apple PowerBook G4 1.25 GHz)
 * 64-bit PowerPC 970fx "G5" (Apple Power Mac G5 1.8 GHz DP)
 * 64-bit PowerPC POWER9 "Sforza" (Raptor Talos II 3.8 GHz)

 All built and passed fate.  I additionally ran the example clip of Big
 Buck Bunny from x265.org in ffplay to great success.
