Subject: [PATCH] Forced commit; previous commit also included: - eliminate a
 malloc()/snprintf()/free() in the native exec(2) case and   in the easy
 emulation environments. - Allow the brand emul_path (ie: /compat/xxx) to be
 NULL rather than   needing it to be an empty string that is always
 referenced.
