Status of Solaris filter symbols support in GNU ld?

I have recently hit a bug where Solaris filter symbols are handled
improperly by GNU ld and linked into resulting executable or shared
library as symbols with absolute address 0x0, instead of linking them as
dynamic symbols to be resolved by runtime linker.
The executable in question obviously segfaults when these symbols are
The original post describing the problem with links to bugreports and
detailed description of how filter symbols work can be found here:
The bugs in question can be observed in Nexenta, that is using GNU ld to
link most of its software, the GNU ld version we use is:

Although I know that there is new upstream version of GNU ld available,
and although I'm already working on integrating it in Nexenta, I have
examined the ChangeLog and have not seen any changes related to Solaris
filter symbols handling, thus I believe that the problem still exists in
2.17.x series of binutils.
Can anyone comment on the status of implementation of this feature in
GNU ld, and also in GNU nm, which seems to be also unaware of the fact
that something like filter symbols exist.
I'm offering my hand to fix the issue if someone will help me to get me
thanx for your time,
