put all the gi files into another directory

[Roelof Wobben <r wobben home nl>]

Hello,

I'm trying to port Cinnamon to Crux Linux.
But now I ran into a big problem.

gobject-introspection installs the .gir files into /usr/share/gir-1.0/

But In Crux linux I'm no allowed to use the /usr/share directory.

So is there a easy way to tell gobject-introspection to put all the .gir 
files into another directory.
That means also the gir files of gtk , atk  and pango

Regards,

Roelof
