It was the workaround for the opposite problem; declared to be in
cairo-gobject, but really in libcairo. 

But in this case there were two issues:
1. the -XLA solution is for the opposite problem (a $linklib cairo-object
that you want to kill), while the problem requires a cairo-gobject to be
linked.
2. for some reason a versioned lib (.so.2) was used in this header. That
might have prevented -XLA even if it was fixable with it.

No, there already is one, http://bugs.freepascal.org/view.php?id=25191

Quick workaround till a more permanent solution is devised : use
smartlinking. Compile at least gtk2 FPC pkg with -CX, and then link with -XX

XLO/XLA has been documented in the buildfaq since 2.0.4 times. 
Basically it is a simple system for substitutions and prioritization on the
combined list of $linklibs for systems with flat linker namespaces. (read:
