Subject: build.sh: Check for lex and yacc.
X-Git-Tag: collectd-4.4.1~5^2^2
X-Git-Url: https://git.octo.it/?p=collectd.git;a=commitdiff_plain;h=ae210a9978f06e6ed7de560b5621ba3d9c761315

build.sh: Check for lex and yacc.

Warn the user, if lex(1) and yacc(1) cannot be found. This is not
necessarily an error, as flex(1) or bison(1) might be available.

As suggested by Kevin Trumbull (onebinary) on IRC.
