[PATCH QGit] Immediately evaluate the ProgramFiles environment variable

[Markus Heidelberg <markus.heidelberg@web.de>]

Commit 50d839b (Don't hardcode GIT_EXEC_DIR for Windows so much,
2009-04-18) broke 'make install' on Windows. Somehow the current working
directory was prepended to the install path given with target.path, when
$(ProgramFiles) should be evaluated during the call of 'make'.
This seems to be a qmake bug with generating the Makefile.

For clarification:
$ cd C:\projects\qgit4\src
$ qmake src.pro -win32 -o Makefile

Now the install_target and uninstall_target targets in Makefile.{Debug,Release}
are wrong, for example

uninstall_target:  FORCE
	-$(DEL_FILE) "c:$(INSTALL_ROOT)\projects\qgit\src\$(ProgramFiles)\Git\bin\$(TARGET)"
	-$(DEL_DIR) $(INSTALL_ROOT)"c:\projects\qgit\src\$(ProgramFiles)\Git\bin\" 

instead of

uninstall_target:  FORCE
	-$(DEL_FILE) "c:$(INSTALL_ROOT)\Programme\Git\bin\$(TARGET)"
	-$(DEL_DIR) c:$(INSTALL_ROOT)\Programme\Git\bin 

Hmm, seems as if there is another bug:
$(INSTALL_ROOT)"c:  vs.  c:$(INSTALL_ROOT)

Sorry for this and for noticing it just a bit too late. I haven't called 'make
install' before.
