9382b3809b overload the existing '-q' flag so that if '-l' and '-q' are used 
together, a "short form" listing (just pathnames) is generated.
change a few flag variables to "smallint" as well.

40f0bcf9d3 fix infinite retry bug. also, reduce per-packet receive timeout 
to something more reasonable than 5 seconds, and add simple
exponential backoff to compensate.  improves performance on
marginal networks.

d2bb2d3918 - Generally strip off -l that does not pull in a lib. 
If l_list is non-empty then add the group flags.

8d91c13df5 - fix bug where we linked again -lm even though it is not needed. 
For BBOX_LIB_LIST="crypt m" trylink ... with just applet true, we pulled in
  libm because in this case we tried to use invalid flags (plain "-l" without
  a lib) which of course failed, thus the script thought that -lm was needed.

  The fix is not to pass "-l" without a lib if we are about to check if any
  or the last remaining lib is really needed.
