Have you tried using the “gnu-build-system” and replacing the configure
phase with your invocation of premake4?

One difference between “guix build” and “guix environment” is that the
latter builds a profile first, so environment variables for libraries or
headers really only have to be set to a single directory
(e.g. $GUIX_ENVIRONMENT/lib or $GUIX_ENVIRONMENT/include).

“guix build”, on the other hand, builds up long chains of directories as
the values for these environment variables.

Did you not have to run premake4 first?  If you don’t need it then it
would be sufficient to use the gnu-build-system and delete the configure
phase.

(I don’t think we need a new build system for the case where just the
configure phase differs slightly, but maybe I’m missing something.)
