I got dynamic libs working fine on sh4 two years ago
at ixia.  I seem to recall a bit of debugging...
guess I used a static system first, then
brought up dynamic linking carefully, using strace and
printf, and maybe gdb/gdbserver.  The trick is to
make each step from the start transparant; then
you can see where it goes awry.  Running the glibc regression
tests is also a great idea.
The linux-sh mailing list
is very helpful even though the archive is broken.

Please post to the linux-sh or crossgcc lists rather than to me
directly.  Then I'm glad to help a bit.
Be sure to mention the versions of gcc/glibc/binutils/linux you're
having problems with.

You're welcome!
