Subject: Makefile: Do not fail build if stale dependency files are present
X-Git-Url: http://git.itanic.dy.fi/?p=scan-pagemap;a=commitdiff_plain;h=72450144a043c057c6cfbf95a5fbb99d7ff80743

Makefile: Do not fail build if stale dependency files are present

If we happen to remove some old header files, the build should not
fail because the header files are still listed in the dependency
files.
