(svn r27588) [1.6] -Backport from trunk:

- Fix: [Build] Force sorting to be locale independent, so files are always ordered the same and by that token better diff-able (r27562, r27558)
- Fix: Typos in comments and string (r27561, r27560)
- Fix: [Build] bashism that caused different CFLAGS with bash vs dash (r27557)
