This release works around bugs, i.e. if a build of 0.12.2 or 0.12.2.1 succeeded (including a run of the test-suite), no update is necessary.

• a workaround that was assumed to be only needed for nvfortran 26.x is also already needed by 25.11
• because CCE crayftn might create upper-case name module files, extra cleanup is necessary to prevent a few harmless file remnants after running configure
• versions 17.x to at least 21.x of crayftn with scalar optimizations active create invalid code for a program in the test-suite
