Problem: Cannot build Haiku in shadow directory.
Solution: Add symlink. (Ozaki Kiichi, closes #6023)
# % make
SHADOWDIR = shadow
-LINKEDFILES = ../*.[chm] ../*.in ../*.sh ../*.xs ../*.xbm ../gui_gtk_res.xml ../toolcheck ../proto ../libvterm ../vimtutor ../gvimtutor ../install-sh ../Make_all.mak
+LINKEDFILES = ../*.[chm] ../*.cc ../*.in ../*.sh ../*.xs ../*.xbm ../gui_gtk_res.xml ../toolcheck ../proto ../libvterm ../vimtutor ../gvimtutor ../install-sh ../Make_all.mak
shadow: runtime pixmaps
