build system bugs for bc 1.06

[Paul Jarc]

I couldn't find a mailing list specifically for bc.  Does it currently
have a maintainer?  Anyway, here are some build system fixes.  The
current version of flex doesn't like the -I and -8 options combined as
-I8; lib/Makefile.in assumes . is in $PATH; and the prototype for
readline() in bc/scan.l is unnecessary and missing a "const".
