BaseTools/BuildEnv: override "set -C" (noclobber) in sourcing shell env

[edk2] [PATCH] BaseTools/BuildEnv: override "set -C" (noclobber) in sourcing shell env

Posted by Laszlo Ersek 7 years, 2 months ago

The BuildEnv utility is sourced (executed by the user's interactive shell)
when the user sets up the build session. Some users like to set -C
(noclobber) for some additional safety in their shells, which trips up
BuildEnv. Update the redirection operator so that it overrides noclobber.
