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 
to libc.a,
but it needs some other changes. I've already have a working solution 
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 
uClibc.

See if the work-around works for you.
