port of findutils to GNU/FreeBSD

[Bruno Haible]

To make GNU findutils 4.1.7 work on GNU/FreeBSD (i.e. FreeBSD kernel
with glibc2) the following patches are necessary.


1) Update config.guess and config.sub to the newest ones,
   ftp://ftp.gnu.org/pub/gnu/config.


2) The autoconf tests would succeed for both FSTYPE_MNTENT (BSD 4.3 API)
and FSTYPE_STATFS (BSD 4.4 API). The situation on FreeBSD is as follows:
The kernel supports the BSD 4.4 API, and therefore an /etc/mtab does not
exist on FreeBSD anymore. And glibc offers the BSD 4.3 <mntent.h> API.
But it does not make sense to use it, because there is no /etc/mtab.

        * configure.in: Prefer the 4.4BSD API to the 4.3BSD API, because the
        latter needs an /etc/mtab, which some 4.4BSD systems don't have.

3) A compilation error in find/fstype.c: FreeBSD does not have the MOUNT_UFS
macro; it doesn't need to because instead it sets the f_fstypename in
'struct statfs' to "ufs". The fix is to not compile the fstype_to_string
function when it is not used.

        * find/fstype.c (fstype_to_string): Don't define this function if
        HAVE_F_FSTYPENAME_IN_STATFS is defined.
