gcc-remap-guix-store.patch raw

   1  Without ffile-prefix-map, the debug symbols will contain paths for the
   2  guix store which will include the hashes of each package. However, the
   3  hash for the same package will differ when on different architectures.
   4  In order to be reproducible regardless of the architecture used to build
   5  the package, map all guix store prefixes to something fixed, e.g. /usr.
