Description Iain Lane 2016-05-10 11:18:40 UTC 
Trying to jhbuild gnome-keyring on my system, I got

  /usr/bin/ld: pkcs11/rpc-layer/gkm_rpc_daemon_standalone-gkm-rpc-daemon-standalone.o: undefined reference to symbol 'dlsym@@GLIBC_2.2.5'
  //lib/x86_64-linux-gnu/libdl.so.2: error adding symbols: DSO missing from command line

Because DL_LIBS wasn't being set to -ldl, as the check only looked for dlopen
and not dlsym too, which fixes the problem.

Attached patch is adapted from glib.

We use both, and they may not both be exposed by libc but by libdl
instead.
