- Subject: [PATCH 1/1] Fix config.mak.uname to allow cross-compilation
-
- Current implementation imperatively sets variables from "uname" output.
- This breaks cross-compilation because uname is run on host while target
- configuration may be different.
-
- Make current behavior a non-imperative default, so it's possible to
- force different values setting make variables.
-
- To cross-compile it will be necessary to explicitly set the various
- uname_X variables to values compatible with target.
- No change is needed with normal host compilation.
- Patch is trivial.
