I'm working with 1.15.3 (we have a release out there, so this is what

I've verified that my issue is still in the latest 1.18.4 version. Here
is my issue:
I have both CONFIG_FEATURE_SHARED_BUSYBOX=y and CONFIG_BUILD_LIBBUSYBOX=y.
Everything was working great until I added selinux and pam.
I started getting linker errors.

I think I have it tracked down to scripts/trylink around line 257.
I think it needs to include the $l_list at that point. Otherwise those
libs aren't included. I can give a patch if you'd like.
Yes, please send a tested patch.
Enclosed is the tested patch.
