toolchain/toolchain-buildroot: add comment about using virtual package infra

Commit "9a8ec9195c toolchain/toolchain-buildroot: migrate to virtual
package infrastructure" made the packages toolchain and
toolchain-buildroot to use the virtual package infra even they being
generic packages.
This works because on package/pkg-virtual.mk when a package do not
define neither _PROVIDES_ or _HAS_ symbols, only _IS_VIRTUAL is set to
YES and _VERSION and _SOURCE are set to empty before relaying the call
to inner-generic-package.

Add a comment explaining why the virtual package infra is used in these
cases.
