Bundled libs found in sox-plugins-freeworld (and therefor sox in Fedora)

[Richard Shaw]

While getting my package reviewed[1] it was discovered that sox is
bundling two libraries, libgsm and lpc10.

libgsm is already available so we're using the configure option to use
the system installed library and patching around configure still
looking for the directory (since it's now removed in %prep)

lpc10 is another problem all together. There doesn't appear to be an
upstream for it although the spandsp-devel package provides the header
it doesn't appear to supply the library (unless it's statically linked
into the main library).

The sox project has modified their bundled version of lpc10 so I guess
I'm asking if we can consider it a fork and leave it alone? I was
planning on adding a virtual provide for lpc10 in case it ever gets
packaged.

Once we figure out a plan I was going to open a bug in Fedora for the
main sox package so they can get their package fixed.

Thanks,
Richard
