[Qemu-devel] [PATCH 13/15] Use a few more gcc warning flags

[Blue Swirl <blauwirbel@gmail.com>]

If the compiler supports the following warning flags, use them:

-Wformat-security -Wformat-y2k -Winit-self -Wignored-qualifiers
-Wmissing-include-dirs -Wclobbered

Currently, these flags don't produce any warnings.
