Subject: Makefile: suppress error messages from 'git'.
X-Git-Tag: v1.1~11
X-Git-Url: http://git.neil.brown.name/?a=commitdiff_plain;h=d3aa70e3c110a0269d8ce5a6a688bcd0ad27e141;p=wiggle.git

Makefile: suppress error messages from 'git'.

If you have a clone of the 'wiggle' git tree but with no
tags, then "git describe HEAD" will complain
   fatal: No names found, cannot describe anything.
As it produces no output, the compiled in default will be used
so this is just an unnecessary message.  So send it to /dev/null.
