[bug#59073] [PATCH v2] gnu: r-minimal: Avoid referencing /gnu/store/[^-]+-glibc-[^-]+-static.

[Christopher Baines <mail@cbaines.net>]

As this causes the following error when computing a cross-compilation
derivation for r-minimal and related packages:

  guix build: error: path ‘/gnu/store/[^-]+-glibc-[^-]+-static’ is not valid

I think this is coming from the string appearing in the builder and thus the
sources section of the derivation, but not being a valid store path.

* gnu/packages/statistics.scm (r-minimal)[arguments]: Split string involving
/gnu/store.
