Message:

footer-pass2-compiling-targets.kmk,VCC100*: Introducing linker output variable OUTPUT_MAYBE_PRECIOUS for files that shouldn't be unconditionally deleted prior to linking. This way it's possible to keep the PATH_STAGE_LIB copy of an import library and only update it when there are real changes to the exports of the DLL we're linking, thus avoiding a relinking cascade.
