Personally I'd prefer to not add more conditional defines in uClibc but
make it a little-bit simpler.

I.e. either Vlad's patch or #1 from this series IMHO looks better.
It's been quite some time since we updated our tools with PCL support
and I'm not really sure if there's anybody interested in using ages old
tools with today's uClibc. We don't test such combinations and there could
be issues already in such combos.

BTW I noticed that Vlad's patch removes/reverts that thing as well:
http://cgit.uclibc-ng.org/cgi/cgit/uclibc-ng.git/commit/ldso/ldso/arc/dl-sysdep.h?id=181d410ad00cddd1d6c9f4835e129136b74
c5187

While Andrew just replaces ".&" construction with "@pcl".
I'm wondering which is the correct approach here?
