[bug#74416] [PATCH v2 2/2] gnu: petsc: Remove store references on make and gcc.

[Lars Bilke <lars.bilke@ufz.de>]

Reduces closure size from 970 MB to around 700 MB for petsc-openmpi
package and also makes `guix pack` packages containing petsc
bit-reproducible (by removing make it removes implicit guile
dependency).
