Some further tests with the same version of binutils on both sh4 and
cross-building on x86_64 using the two object files attached to this bug report
with the linking working fine on x86_64 while failing on sh4.

As you can see, the eh_frame sizes differ for test2.o, for test1.o they are
unrelaxed and identical.

We are currently speculating whether this is a bug in binutils or in the
compiler used to compile this particular version of binutils on sh4 is to be
blamed since the earlier, working version of binutils on sh4 was compiled with
an older version of gcc.
