I got it (thanks Janis) and as the testsuite changes are useful
on their own (i.e. without a "noisy truncation failure"), I've
committed it.

Uh, I dunno, I haven't looked closely.  There is lseek support
(if it had failed, I wouldn't have seen the "noisy error"
message ;) so it's not *that* trivial.  But maybe there are bugs
in that support.  FWIW, some are calls to abort:
 program stopped with signal 6.
some are:
 Fortran runtime error: End of file
and some are link errors for stuff required but not present:
chmod_1.f90:(.text+0x174): undefined reference to `__gfortran_chmod_i4_sub'
chmod_1.f90:(.text+0x192): undefined reference to `__gfortran_access_func'
chmod_1.f90:(.text+0x1e0): undefined reference to `__gfortran_getuid'
(etc.)  No whole-sale cleanup at this time.
