I hope you will not regret this sentence once you see my "one-liner":
$ cat manifest.scm
;; What follows is a "manifest" equivalent to the command line you gave.
;; You can store it in a file that you may then pass to any 'guix' command
;; that accepts a '--manifest' (or '-m') option.
(specifications->manifest (list "gcc-toolchain"))
$ printf '(use-modules (guix packages) (guix derivations) (guix store) (guix
profiles) (guix scripts environment) (guix scripts size)) ((@@ (guix scripts
size) display-profile) (run-with-store (open-connection) ((@@ (guix scripts
size) store-profile) (map (λ (entry) (derivation->output-path (run-with-store
(open-connection) (package->derivation (manifest-entry-item entry)))))
(manifest-entries (load-manifest "manifest.scm"))))))' | guix repl /dev/stdin

The code is based on the "hack at it until it works" approach, not on the "ok so
I should first try to understand store monads" approach, so I am sure there are
issues with it. But on my simple example it seems to work. The path
("manifest.scm") is hard-coded though.
