that is the problem.

ok no -z,defs in there, guess that means that when linking libraries it
will not be detected when symbols are missing, which causes link
failures later in the build when the broken libraries are used.

usually libs should contain not just search paths but also the libraries
to be linked, e.g. in with a system nss i get:

  export NSS_LIBS=$(gb_SPACE)-lssl3 -lsmime3 -lnss3 -lnssutil3 -lplds4
-lplc4 -lnspr4 -lpthread -ldl

also i guess only Sun ld knows -R, the GNU ld equivalent is -Wl,-rpath,

of course unopkg.bin does not use nss libraries itself so no point
linking to them.  the problem is that libvcl is not properly linked
against nss.

i suggest you copy the -Wl,-z,defs line from to then
rm -r workdir/*/LinkTarget and see what breaks then.
