Pkg seems to read dependencies from non-sysimage stdlibs from the stdlib project, even if loaded externally #3498
Description
Causes things like
ERROR: LoadError: ArgumentError: Package SparseArrays does not have SuiteSparse_jll in its dependencies:
- You may have a partially installed environment. Try `Pkg.instantiate()`
to ensure all packages in the environment are installed.
- Or, if you have SparseArrays checked out for development and have
added SuiteSparse_jll as a dependency but haven't updated your primary
environment's manifest file, try `Pkg.resolve()`.
- Otherwise you may need to report an issue with SparseArrays
when trying to load SparseArrays master in another package.
