[Buildroot] [PATCH 5/5] fs: ensure $(TARGET_DIR_WARNING_FILE) is writable

[Yann E. MORIN]

From: "Yann E. MORIN" <yann.morin.1998 at free.fr>

If the Buildroot tree is read-only, then $(TARGET_DIR_WARNING_FILE) is
copied read-only into target/ but we may want to remove it during the
build process.

This poses no real problem, since target/ itself is guaranteed to be
writable, but for good measure, force $(TARGET_DIR_WARNING_FILE) to be
writable itself.
