  Yep, don't be discouraged by the large amount of feedback :-)

  It would be good to repeat this comment in the .mk file. That helps to 
see if a certain packaged upstream version is in fact more recent than 
what is already there.

  I prefer AIRCRACK_NG_MAKE_OPTS.

  I would add an else branch that explicitly sets sqlite=false, to make 
sure it doesn't leak in through the environment.

  The solution is simple:

AIRCRACK_NG_MAKE_OPTS += LIBSQL="-lsqlite3"

(no -L is needed because libsqlite3.a is in the default library search path).

  If it works, I prefer to put the TARGET_CONFIGURE_OPTS in the 
environment instead:

$(TARGET_CONFIGURE_OPTS) $(MAKE) -C $(@D) $(AIRCRACK_NG_MAKE_OPTS) all

That gives the Makefile the possibility to append to CFLAGS and LDFLAGS, 
if necessary. However, some Makefiles unconditionally set CFLAGS or 
LDFLAGS (or even CC), in that case passing through the environment 
doesn't work.
