pass correct --with-flint to eclib's configure

[dimpase]

It's reported in [this thread on sage-devel https://groups.google.com/d/msg/sage-devel/OJJFRAgvtqk/JZMEdA81EAAJ]
that "wrong" libraries in /lib may shadow the "right" one in SAGE_LOCAL/lib for eclib (this happens with libpari)

It appears to be due to --with-flint="" being passed instead of
--with-flint in spkg-install of eclib, adding a spurrous -L/lib to the ld search path for building eclib

Upstream: None of the above - read trac for reasoning.

I've opened JohnCremona/eclib#57 to make eclib more consistent, but will not rely on this accepted to fix this bug.

this could be removed once a new eclib version with https://github.com/JohnCremona/eclib/pull/57 is in Sage.
