Does the linknamespace test perform a full link, and fails if it 
encounters undefined symbols?

I don't think anyone has the requisite static NSS libraries for linking 
libcrypt statically with --enable-nss-crypt.  So you may have to disable 
this for $(nss-crypt) configurations.

Carlos will submit a patch to do this for elf/tst-linkall-static.  We 
weren't aware of this issue until this new test went in.

Thanks,
Florian
