x86/purgatory: Avoid creating stray .<pid>.d files, remove -MD from KBUILD_CFLAGS
The kernel build system already takes care of generating the dependency files. Having the additional -MD in KBUILD_CFLAGS leads to stray .<pid>.d files in the build directory when we call the cc-option macro. Signed-off-by: Sven Wegener <sven.wegener@stealer.net> Cc: H.
