Circular dependence between "bison" and "gettext-tools" under Solaris

[Matthias Scheler <tron%zhadum.org.uk@localhost>]

        Hello,

I'm trying to use "pkgsrc" on a Solaris 10 amd64 system. At some point
it tries to build "bison" which fails because of a circular dependence:

ERROR: Circular dependency detected
*** Error code 255

Stop.
bmake: stopped in /content/pkgsrc/devel/bison
*** Error code 1

The chain is:
- "bison" wants "msgfmt" which comes from "gettext-tools".
- "gettext-tools" wants "libtool"
- "libtool" wants "f2c"
- "f2c" wants "yacc" which isn't defined under Solaris and "pkgsrc
  "therefore" tries to use "yacc"

The following change seems to fix that:

Is that the correct solution? There is of course the risk that
"/usr/ccs/bin/yacc" isn't good enough to build some random
other package.

        Kind regards
