This is a bit vague. Which bug? Which commit? Do you have some more
details ?

Perhaps:

ifeq ($(BR2_mips)$(BR2_mipsel)$(BR2_mips64)$(BR2_mips64el):$(BR2_MIPS_SOFT_FLOAT),y:y)

I'm wondering if we shouldn't introduce some global BR2_ARCH_IS_MIPS
option, or something like that, because we have a lot of places where
we repeat those mips/mipsel/mips64/mips64el conditions. But that is of
course a completely separate discussion.

Best regards,

Thomas
