liquid-dsp: pass the supported x86 CPU extensions 

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.

Fixes:
