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