Here 'time make install' *after* make install says this:

real    1m56.868s
user    0m29.270s
sys     0m17.049s

And 'touch ../../gtk+/gtk/gtktextview.c && time make'
produces this:

real    1m17.363s
user    0m30.982s
sys     0m15.749s

Somehow libtool relinks every library on 'make install',
and relinks every library which depends on libgtk
on 'make' if libgtk was rebuilt.

Are you sure you were talking about toplevel gtk directory,
not about 'make' inside gtk+/gtk? Because that says:

touch ../../../gtk+/gtk/gtktextview.c && time make
real    0m23.437s
user    0m10.881s
sys     0m3.368s

Disabling tests would make things faster, but only
inside gtk+/gtk, if you go up then you get modules
(many) relinked anyway.
