yate: clean up CONFIGURE_ARGS

yate: clean up CONFIGURE_ARGS

- remove ARGS that are default anyway
- enable sse2 when target is x86_64
- remove --enable-inline as that causes too many warnings:

    ilbccodec.cpp:50:7: warning: inlining failed in call to 'virtual {anonymous}::iLBCFactory::~iLBCFactory()': call is unlikely and code size would grow [-Winline]
     class iLBCFactory : public TranslatorFactory
           ^~~~~~~~~~~
    ilbccodec.cpp:50:7: note: called from here
     class iLBCFactory : public TranslatorFactory
           ^~~~~~~~~~~

- --enable-internalregex removed as yate can use external regex
- make some choices depending on whether a package is selected; otherwise the
  build might fail, i.e. when spandsp is not installed but the Makefiles tells
  the build system to use spandsp anyway
