This change provides a sample rate converter (SRC).
The SRC is polyphase FIR type. All the conversions coefficients tables are
automatically generated by a separate Octave scripts set in the rimage
tools set. The supported in/out rates and the performance can be customized
for a different quality/resources trade-off.
In order to use native XTENSA compiler the core target needs to
be overwite with the good platform. This patch is adding an optional
option in order to be able to overwrite the core selection.
Example:
- Set Xtensa export PATH=$PATH:<PATH>/xtensa/XtDevTools/install/tools/RD-2012.5-linux/XtensaTools
./configure --with-arch=xtensa --with-platform=baytrail --with-dsp-core=CHT_audio_hifiep --with-root-dir=<PATH>/xtensa/XtDevTools/install/tools/RD-2012.5-linux/XtensaTools --host=xtensa CC=xt-xcc OBJCOPY=xt-objcopy OBJDUMP=xt-objdump

The tool-dir naming was a bit ambiguous so rename and fix build-all.sh
to use new name too.

This project provides an open source audio firmware infrastructure for audio
DSPs found on many modern devices. The intention is to allow developers to
create their own codecs, audio processing algorithms and pipelines using
the infrastructure and audio components provided by this project.
The project currently supports the Intel Baytrail and Cherrytrail audio DSP
platforms which use the Xtensa architecture.
The firmware source code is released under the BSD 3 clause licence.
