Problem: configure seems not to make missing yacc/bison fatal, so we find the missing dependency at build time.

  YACC     parse_tab.c
../config/ylwrap: line 176: yacc: command not found
make[1]: *** [Makefile:545: parse_tab.c] Error 127
make[1]: Leaving directory '/home/garlick/proj/powerman/powermand'
make: *** [Makefile:457: all-recursive] Error 1

Still an issue. We are using AC_PROG_LEX and AC_PROG_YACC which do not fail if the programs aren't found. Add some logic to do that.

build: fail if bison/flex are not available
47f87af 
Problem: if flex or bison are not installed, configure
lets the build continue and fail.

Ensure that if those programs are missing, configure fails.

Fixes chaos#40
