Use the libreadline in Winedbg, if available

winedbg _binaries_ compiled with --enable-readline quite possibly.

As far as the source code to winedbg is concerned 
maybe but probably not. It might depend on whether 
--enable-readline or --disable-readline is the default,
but that remains to be tested in court, but it is not 
certain it matters at all. The court might quite reasonably
rule that no linking to readline has taken place yet and
thus no derived work can have been created and even if they
hold that some sort of linking has taken place it might not
consider it a derived work.

In short linking, especially potential linking, do not
always imply a derived work which is all that matters
as far as the law is concerned.

Also note that I'm not convinced that any court will hold
that the GPL is different from the LGPL in any relevant
way with the possible exception of in bad faith trying
to circumvent the requirements by trying to be "clever".

Of course it is a little unclear that you really can
do unlawful circumvention of license requirements.
This is a like claiming that somebody circumvented
trespassing your land by moving around it. Either
you trespass or you do not. Either you violate
the license or you do not.

The analogy is quite good even in other areas:
Even if you are on somebodies land you do not nessary
trespass either because of copyright like "fair use"
requirements in the law of most countries.

As a sidenote:
In Sweden "fair use" concerning trespass is so extensive
that I never heard about _any_ case concerning it.

Only the debugger (winedbg) links with readline =>
only the debugger can be effected.

Trying to claim, even though you didn't, that Winelib is 
effected is absurd since it is independent of the debugger.
Distributing the debugger with WineLib is merly an aggregation
nothing more.
