build-aux/install-sh should be executable

[Vincent Lefevre]

Hi,

There's a bug in texinfo 4.11: the file build-aux/install-sh isn't
executable. In general, this is not a problem since it is called
with $(SHELL), but if there is no mkdir from the coreutils, this
script is executed via:

  else
    # As a last resort, use the slow shell script.  Don't cache a
    # value for MKDIR_P within a source directory, because that will
    # break other packages using the cache if that directory is
    # removed, or if the value is a relative name.
    test -d ./--version && rmdir ./--version
    MKDIR_P="$ac_install_sh -d"
  fi

(from the configure script). So, it needs the x bit set.

Regards,
