Makefiles choke sometimes on * and \ characters

[maelh]

For example langbindings\java\make_win64.txt

Would not execute @-sildel /Q amzi\ls\*.class properly and instead execute @-sildel /Q amzi\ls*.class, i.e., omitting one backslash, and therefore fail. Addiing quotes around "amzi\ls\*.class" fixed the issue.

There might be other places in makefiles, that are affected by it. Before changing them all, look up how GNU make handles paths and * and \ etc. under Windows.
