Adding '--disable-fuse' to CONFIGURE_ARGS avoids the attempt to build in fu=
se
support and thus avoids building block_export_fuse.c which contains the FAL=
LOC*
linux-isms.  FUSE support won't work on FreeBSD without porting that code, =
so
disabling it for now is reasonable.

A better fix (perhaps a change that could be submitted upstream) might be a=
 way
to write that code in a way that is portable to non-linux OS's.
