Subject: MSVC: Broken ifx needs new $TMP (#42155)

Certain versions of ifx (the majority of those available) have an issue
where they are not compatible with TMP directories with dot chars
This precludes their use with CMake.
Remap TMP to point to the stage directory rather than whatever the TMP
default is
