[PATCH] KVM: selftests: add -MP to CFLAGS

[David Woodhouse]

From: David Woodhouse <dwmw@xxxxxxxxxxxx>

Using -MD without -MP causes build failures when a header file is deleted
or moved. With -MP, the compiler will emit phony targets for the header
files it lists as dependencies, and the Makefiles won't refuse to attempt
to rebuild a C unit which no longer includes the deleted header.
