[Swan-dev] Bison rule

[D. Hugh Redelmeier]

I just poked at the Bison rule in out lib/libipsecconf/Makefile

I hope that the plan9 filesystem problem that Antony encountered
remains fixed.  Instead of a cat, I used a mv.

I noticed that $(builddir) is . when this rule fired.  Is this always
going to be the case?  If so, the recipe can be simplified further.

|     libipsecconf makefile: simplify Bison rule and make it more robust
|     
|     - the rule previously assumed that the grammar was parser.y.  Now it
|       supports anything matched by the pattern
|     
|     - two sed commands combined into one
|     
|     - g flag removed from sed s subcommands
|     
|     - sed command now only applies to lines that start with #
|     
|     - comments improved
|     
|     - the recipe uses a single cd command
