Yes, as per updated patch set, also uploaded.

The sh.ld linker script does have the necessary SECTION_eh_frame define.
But older SH targets have not been updated to use it. In fact the only one
that does is the sh4_202_md. Something to note down for after the code freeze.
In a slight change of plan, I think I'll wait until you're finished
looking at all the targets before starting even the SH cygwin build -
given the recent report it seems like it may be wise to rebuild all the
cygwin tools with statically linked GMP and MPFR. I have no desire to
rebuild them all more than once, so let's wait to see if your experiments
show up more issues down to the tools.
