These ports starting failing on gold linker with messages like:
./.libs/libspice-client-gtk-3.0.so:
error: undefined reference to 'XGetPointerControl'
./.libs/libspice-client-gtk-3.0.so:
error: undefined reference to 'XChangePointerControl'
The problem and fix was already described here:
https://bugs.freedesktop.org/show_bug.cgi?id=97383
Apparently USES=pathfix and USES=autoreconf can't be used together, so
the pkgconfig directory is now passed via MAKE_ARGS
While here, fix py-spice-gtk install error by removing non-installed file
from the pkg-list.
