This is needed in order to have separate multilib intercept hooks.

This will allow to register, in a single postinstall, multiple hooks.

Postinstalls that use qemu are throwing a segmentation fault when
building for qemux86-64 on a 64bit host (it might also happen for
qemux86 if building on a 32bit host but I didn't test). It looks like
qemu looks for ld.so.cache which is not found because it is generated
after rootfs_(rpm|ipk|deb)_do_rootfs is called and then it tries to load
libraries from the default paths (which are the host's). In order to
avoid this, pass the LD_LIBRARY_PATH explicitly to the target's dynamic
loader.

"Link" the package to the postinstall hook by running the
postinst_intercept script.

All font packages should inherit this class in order to generate the
proper postinst/postrm scriptlets.

The scriptlets will actually create a host intercept hook that will be
executed at the end, at do_rootfs time, after all packages have been
installed. This is good when there are many font packages.
