Subject: [CMake] Simplifying logic for USES_TERMINAL on bootstrap targets.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=d3e2cf00b20bf6495102e125302623414efc1997;p=clang

[CMake] Simplifying logic for USES_TERMINAL on bootstrap targets.

In CMake variables that haven't been set are evaluated to empty strings, so we don't need to set the variables to empty strings.
