Before the patch an undefined constant EFI_SUBSYSTEM was used in the crt0 code. The current version of binutils does not swallow the error. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=888403 The necessary constant IMAGE_SUBSYSTEM_EFI_APPLICATION is already defined in pe.h. So let's factor out asm-generic/pe.h for the image subsystem constants and use it in our assembler code. IMAGE_SUBSYSTEM_SAL_RUNTIME_DRIVER does not exist in the specification let's use IMAGE_SUBSYSTEM_EFI_ROM instead. The include pe.h is only used in code maintained by Alex so let him be the maintainer here too.
