[PATCH] build: avoid link failure on systems using gnulib's fcntl but not open

[Jim Meyering]

I noticed this build failure for grep:

    http://hydra.nixos.org/build/329919

      CCLD   grep
    Undefined symbols:
      "_rpl_open", referenced from:
          _grepfile in grep.o
    ld: symbol(s) not found
    collect2: ld returned 1 exit status
    make[2]: *** [grep] Error 1

I fixed it with this change to grep, and do appreciate
the implied warning that grep needs the "open" module,
but this must be a bug in gnulib...

* bootstrap.conf (gnulib_modules): Using gnulib's fcntl module
and including <fcntl.h>, but not also using gnulib's "open" module
would result in link failure due to references to rpl_open
on systems requiring the replacement (e.g., Cygwin and Darwin).
