It /is/ visible under its normal name: the package name is different
from the variable name.  What matters for ‘guix package’ is the ‘name’
field, not the name of the variable.

BTW, in the meantime it’s always possible to install pkg-config with
something like:

  guix package -e '(@@ (gnu packages pkg-config) %pkg-config)'

which directly refers to the variable.
