This doesn't support "include" directives.

Also, it's ugly that you have to compile files per-target.

Perhaps you can use something like:

CONFIG_NOT_ACPI   := $(call lnot,$(CONFIG_ACPI))
CONFIG_NOT_SMBIOS := $(call lnot,$(CONFIG_SMBIOS))

common-obj-$(CONFIG_ISA_IPMI) += isa_ipmi.o
common-obj-$(call land,$(CONFIG_ISA_IPMI),$(CONFIG_ACPI))     += isa_ipmi-ssdt.o
common-obj-$(call land,$(CONFIG_ISA_IPMI),$(CONFIG_NOT_ACPI)) += isa_ipmi-ssdt-stub.o
common-obj-$(call land,$(CONFIG_ISA_IPMI),$(CONFIG_SMBIOS))   += isa_ipmi-smbios.o
common-obj-$(call land,$(CONFIG_ISA_IPMI),$(CONFIG_NOT_ACPI)) += isa_ipmi-smbios-stub.o

# Make toplevel always build these
common-obj-$(CONFIG_ALL) += isa_ipmi-ssdt-stub.o isa_ipmi-smbios-stub.o
