Installed tests - parallel installability

[Sébastien Wilmet <swilmet gnome org>]

Hi,

Currently the installed tests [1] of libraries are not parallel
installable.

For example the GTK+ tests are installed in:
.../installed-tests/gtk+/

When GTK+ 4 will be released, it would be nice to still run the GTK+ 3
tests. Especially because GTK+ 3 will be advertised as more stable. But
I guess this is true for any library (except when security holes are not
fixed in old versions).

So for GTK+ 3, the tests should probably be installed in:
.../installed-tests/gtk+-3.0/

No?

Sébastien
