Subject: Log lex/flex detection errors in the config log
X-Git-Tag: openafs-devel-1_5_76~76

Log lex/flex detection errors in the config log

When we detect if lex is flex, we run 'lex --version', which may
complain to stderr if lex is not flex. Instead of printing such errors
to the person running 'configure', redirect stderr to config.log along
with stdout.
