When a powerpc target is detected the build system tries to force
altivec support but that's wrong:
Not every powerpc processor has altivec instruction support.
It's using the removed/deprecated -faltivec compiler directive when it
should be using -maltivec instead.
Even if the above conditions are corrected the altivec codepath fails
to build properly.
So just disable altivec in general using the standard
--enable-simdoverride configure option. Fixes:

By default, the liquid-dsp configure script looks at the current CPU
to find which x86 CPU extensions are supported. Those checks use
AC_TRY_RUN(), which cannot work in a cross-compilation environment,
and would anyway be wrong.
To fix this, we explicitly pass the appropriate ac_cv_have_<foo>_ext
autoconf cache variables.

[Thomas:
- add patch to fix autoreconf issue, and use LIQUID_DSP_AUTORECONF =
YES instead of an horrible hack calling aclocal/autoconf manually.
- use the github macro instead of hand-coding <pkg>_SITE and
<pkg>_SITE_METHOD. This allows to remove <pkg>_SITE_METHOD
entirely.
- use a full hash as the <pkg>_VERSION
- remove trailing whitespace everywhere.
- use one single assignment of LIQUID_DSP_CONF_OPTS
- fix the comment about the eglibc/musl dependency (it was only
mentioning eglibc, and the condition was inverted)
- add the musl/glibc dependency on the package option itself
- make the package depend on dynamic library support, since the
makefile unconditionally builds a shared library.
- add hash file.]
