Comment (by fbissey):
Actually info from sage-on-gentoo which is all compiled with `-as-needed`
suggest a slightly different approach:

Neither of those get libntl and they don't get liblinbox either. All the
libraries are resolved so they are definitely not needed. Furthermore
liblinbox doesn't need libntl. Only liblinboxsage does and curiously I
don't think we ever link to it.

In the first instance Jeroen's latest commit would solve the present
problem though.
