Log Message:
Updated awka to 0.7.5 to fix pkg/17112.

>From CHANGELOG.txt:

v 0.7.5, June 20 2001

*  Gawk 3.1.0's Coprocessing and inet functions are now supported by Awka,
   as are the new builtin functions asort() and mktime().  Thanks to Juergen
   Kahrs for the original work to implement this excellent feature, and to
   Arnold Robbins for including it in Gawk.  That libawka will now be
   distributed under the GNU General Public License (GPL) rather than
   LGPL as a result of having to include some code from Gawk.  The previously
   separate dfa library is now absorbed into libawka, and the -d command-line
   option for awka removed as it is no longer needed.
*  The match() function has been extended to support its new capability in
   Gawk 3.1.0.  See the Gawk manpage for details.
*  awka -a -v 'var="string with whitespace"' will now work correctly.
*  To avoid breaching ANSI-C guidelines, \r in AWK program strings will
   be preserved as \r in the generated C code, not converted to ASCII
   character 13.  Previously some platforms were incorrectly treating
   \r as \n - this has been fixed by this change.
*  Fixed a problem wherein awka -c sometimes failed to output matching
   curly braces in the translated code.
*  Fixed a data-input parsing error that could occur when RS="".  The new
   test rsnul1nl (from gawk-3.1.0) will ensure the buglet doesn't return.
*  A new hash routine was implemented providing fewer collisions, particularly
   with long string indexes that have only minor differences.  The optional
   SLOW_HASH #define is no longer needed.
*  Translator now tracks the datatype of scalar variables, and will produce
   more efficient code for vars that stay one type throughout a script.
   This is the first optimisation of translated code in a long, long time
   and it makes a considerable difference to many scripts.
