We may introduce BR2_ARCH_HAS_ELF_SUPPORT as an hidden option which is set to y
by default except for BR2_bfin, BR2_m68k and BR2_cortex_m3. (like for BR2_USE_MMU)

config BR2_ARCH_HAS_ELF_SUPPORT
	bool
	default y if !(BR2_bfin || BR2_m68k || BR2_cortex_m3)

What other developer think ?

Best regards,
Romain
