As a work-around, you may try to arrange your makefile to link statically
against libdl.a where actually _dl_iterate_phdr is defined.
The final solution consists of moving the _dl_iterate_phdr from libdl.a=20
to libc.a,
but it needs some other changes. I've already have a working solution=20
for uClibc-nptl
for sh4, but this is still missing from the trunk.
I'm working to merge it to trunk asas. Then you need to use the latest=20
uClibc.

See if the work-around works for you.
