Support for PowerPC BE

[barracuda156]

Given Makefile has commented out line #CFLAGS += -DBIGENDIAN, support for PPC either existed before or is planned to be added? At the moment build for ppc fails with gcc-4.2 (this is after I added definitions to Makefiles to not use Intel SSE):

With gcc12 the build succeeds, though with a number of warnings 'always_inline' function might not be inlinable.

svacchanda$ port -v installed ssrc
The following ports are currently installed:
  ssrc @1.33_0 (active) requested_variants='' platform='darwin 10' archs='ppc' date='2022-08-21T03:23:09+0800'

Nevertheless, I tried using the binary, and it seems not to work as intended:

svacchanda$ /opt/local/bin/ssrc --bits 24 /Users/svacchanda/Desktop/PinkPanther30.wav /Users/svacchanda/Desktop/PinkPantherTEST.wav
Shibatch sampling rate converter version 1.33(single precision)

Error: Only PCM is supported.
