We are using that 3.X version that you are talking about (Bernardo's 3.4.3)
successfully with shared libraries.
It's on my ever-growing list of "Things To Do" to get us forward onto the
GCC 4.x line... someday... Real Soon Now(TM)
So I can't comment as to whether the 4.x series works, but the 3.4.3 on
uClinux.org does.
We did have a problem with C++ programs and shared libraries at some stage
due to linking issues and we came up with this patch to the 3.4.3 source.

In my original post to this list about this patch I said:
"Bear in mind that if you are using one of the newer linkers that fully
support merged sections you will always have this problem if you are using
the uClinux/elf2flt mechanism when linking with any objects/libraries that
were not built using the "no-merge-constants" flag, because they will not
line up with their relocatable counterpart files.
And that goes for *all* of the files you are linking in, e.g. don't forget
you will have to rebuild libgcc etc. with no-merge-constants.
We found that all way too painful here, so we've patched the linker so that
linking with -Ur also causes merging (so this lines up with the .gdb
absolutely linked file which does merging).
This seems to be working for us so far (fingers crossed)."
And it has kept working for us.... So far.. :)
Hope this helps.
