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.
|
||
|
|
|
||
|
|
We might be able to drop this in favour of using --with-nonshared-cflags
|
||
|
|
when we being using newer versions of glibc.
