Matthieu Castet b4e806b2b9 pld instruction are used in libavcodec/armv4l/dsputil_arm_s.S which can be used
on armv4 that doesn't support this instruction. Futhermore pld is a nop on some
armv5 processor like arm926. Detect if pld is supported and have the
preprocessor remove it when it's not supported.
Fixes issue 393.
