Yann E. MORIN 02fe7c747b package/pkg-generic: don't exclude virtual packages from packages list 
Currently, with a configuration with an internal toolchain, and no other
package is selected [0], especially when one wants to generate an SDK or
a pre-built, pre-installed toolchain, running 'make' will only build
glibc (and its dependencies), and not the full toolchain, as one would
have expected, so there would be no host-final-gcc.

The reason is that 'toolchain' is a virtual package, so it is excluded
from PACKAGES, the list of packages enabled in the configuration. so it
is not a dependency of target-finalize, and so nothing pulls it in the
build.

The reason for excluding virtual packages from that list is not obvious.

When virtual packages were introduced in 7439824412 (packages: add
infrastructure for virtual packages), there was no BR2_PACKAGE_FOO
symbol for virtual packages (but there was BR2_PACKAGE_HAS_FOO), so
there was no telling that the virtual package was enabled, like we had
for the other kinds of packages (normal, bootloader, toolchain, or linux
kernel).

That caused issues, so in f674c428c2 (core/pkg-virtual: do not check
they are neabled [sic]), and then 3e1b33a534 (pkg-generic: improve
incorrectly used package detection), we explicitly excluded the virtual
packages from causing a build failure when something depended on them,
as we could not yet now whether a virtual package was actually enabled
or not.

Then, in 842ba7ecef (pkg-generic: fix rdepends and phony targets of
virtual packages), we eventually associated a virtual package to is
BR2_PACKAGE_HAS_FOO, which allows treating virtual packages like the
other kinds of packages. There, we explicitly kept virtual packages out
of the list, though (the reasoning was that virtual packages install
nothing in host/ or target/, so they do not directly contribute to the
final content, so we do not need to rsync them, so this was an
optimisation).

However, virtual packages are in fact actual generic packages, and it is
possible for virtual packages to actually provide content for the final
image. Even though we do not have any virtual package that has actual
_INSTALL_CMDS, we still have udev that provides a user for example;
virtual packages in br2-external trees may also very well provide
install commands (e.g. to install files common to their various
implementations).

So, there is currently no technical reason to exclude virtual packages
from PACKAGES, the list of packages enabled in the configuration.

Drop the excluding condition, and always add enabled package, whatever
their kind, to the list of enabled packages.

# Generic package infrastructure
#
# This file implements an infrastructure that eases development of
# package .mk files. It should be used for packages that do not rely
# on a well-known build system for which Buildroot has a dedicated
# infrastructure (so far, Buildroot has special support for
# autotools-based and CMake-based packages).
#
# See the Buildroot documentation for details on the usage of this
# infrastructure
#
# In terms of implementation, this generic infrastructure requires the
# .mk file to specify:
#
# 1. Metadata information about the package: name, version,
# download URL, etc.
#
# 2. Description of the commands to be executed to configure, build
# and install the package

# $$(TARGET_DIR), $$($(2)_VERSION), etc. Also all make functions should be
# referenced with a double dollar sign: $$(subst), $$(call), $$(filter-out),
