9b6b681624 Following r226271, allow disabling lzma support with "WITHOUT_LZMA_SUPPORT".
Correct r226271 which should have used WITHOUT_BZIP2_SUPPORT per r166255.

68f42e1da4 - Create links to the xz and lzma versions even if BSD grep is not the
default. Nor GNU nor liblzma in base provides such functionality so
  it may be useful.

f20f6f3fdf Update BSD grep to the latest development version. It has some code
backported that was written for the TRE integration project in Google
Summer of Code 2011.  This is a temporary solution until the whole
regex library is not replaced so that BSD grep development can continue
and the backported code gets some review and testing.  This change only
improves scalability slightly, there is no big performance boost yet
but several minor bugs have been found and fixed.

48a16a34d8 Remove redundant assignments to WARNS.
For these directories, WARNS is already implied to be 6.

a23d1c70b3 Build and install a BSD licensed grep.
If WITH_BSD_GREP is not set, it will be 'bsdgrep' and GNUgrep will be
'[ef]grep'.  Otherwise, BSD-grep will be the grep family, and GNUgrep
will be 'gnugrep'.

4dc88ebedf Add BSD grep to the base system and make it our default grep.
Deliverables: Small and clean code (1,4 KSLOC vs GNU's 8,5 KSLOC),
              lower memory usage than GNU grep, GNU compatibility,
              BSD license.

TODO:         Performance is somewhat behind GNU grep but it is only
              significant for bigger searches.  The reason is complex, the
              most important factor is that GNU grep uses lots of
              optimizations to improve the speed of the regex library.
              First, we need a modern regex library (practically by adopting
              TRE), add support for GNU-style non-standard regexes and then
              reevalute the performance issues and look for bottlenecks.  In
              the meantime, for those, who need better performance, it is
              possible to build GNU grep by setting WITH_GNU_GREP.
