[Xen-devel] [PATCH] EFI: fix tool chain capabilities detection

["Jan Beulich" <JBeulich@xxxxxxxx>]

Commit f5a54e92 ("xen: move some arch CFLAGS into the common Rules.mk")
transformed CFLAGS assignments to CFLAGS-y ones, which collides with
the was xen/arch/x86/efi/Makefile determines whether the tol chain is
usable for an EFI build. Transform the block back to using CFLAGS.
