Joerg Bornemann 7a1bc0d3ff fix race in debug_and_release builds of static libs for Unix
Consider a debug_and_release build of a static library.
Set DESTDIR to different values for debug/release.
Let TARGET be the same for debug/release.
Now qmake would generate code in Unix Makefiles like this:
  rm mylib.a
  ar mylib.a ...objects...
  rm debug/mylib.a
  mv mylib.a debug/mylib.a
and for release analogous. This clashes when building in parallel.

This patch resolves this conflict by reducing the commands to:
  rm debug/mylib.a
  ar debug/mylib.a ...objects...

We believe that every ar implementation that's in use for Qt
is able to operate on files in subdirectories.

[ChangeLog][Important Behavior Changes][qmake][Unix] QMAKE_POST_LINK
steps of static libraries are now required to operate on $(TARGET) in
$(DESTDIR) instead of $$OUT_PWD. This matches the Windows backends.
