Yes, "--enable-debug=yes".

You'd have to add it like this:

CONFIGURE_ARGS += --enable-debug=yes

PKG_DEFAULT_OPTIONS is only for the option.mk framework. You
can't use it for arbitrary switches.

No, nothing like that. It just enables some runtime consistency checks etc. It
has nothing to do with compiler flags. For debugging with GCC, you should
always compile with -g3 -O0 in your CFLAGS. I would not recommend using this
regularly because it causes a significant performance penalty especially if
you compile a library with this.
