[Bug gold/10238] Gold linker does not resolve symbols using indirect dependencies

I also hit this and I must admit it is slightly confusing at first. We were
linking -lnss3 which works fine with GNU ld, but with GNU gold you suddenly get
lots of unresolved references to PR_ functions. If you know about this
bug/feature then it is easy to figure out you need to add -lnsrp4 explicitly.
But otherwise (especially in a large final link command) it is a bit mystifying
why the "replacement linker" didn't work.

Spot the missing -lnspr4 in the above :)
