wingo has been working on a new GC for guile that supports ephemerals, 
so I don't think this patch will be necessary anymore.

Closing,
Maxime.

Hi guix,

Disclaim procedures do not seem to be used in the wild,
but seem useful for implementing ephemerons in Guile
(to be investigated), hence this patch.

Guile seems to start building fine when using a bdw-gc packave
with "--enable-disclaim" added (I'm using (package (inherit ...) ...),
but that was on master. I'll verify on core-updates, but building
things will take some time.

Greetings,
Maxime.
