Thank you for your proposal; however I'm a little concerned as to continuing using the current compiler detect logic for testing uninstalled GCC as it may incorrectly pick a compiler already present on the system rather than the newly built one. I think the way it's done in gcc/ by using the configured $CC, etc. is the correct one and we should strive to replicate it across top-level libraries as well. I'll give your proposal a shot and I'm lucky enough to have a build configuration where I can have no compiler preinstalled, so at least I can check if testing with your change applied correctly picks the newly built uninstalled compiler in that case.
