Thanks a lot for the investigation and fix! I've applied as-is as it is
the most immediate fix.
However, I am wondering if we shouldn't make BR2_MIPS_NABI32 *not*
select BR2_ARCH_IS_64. Indeed, for most packages (which are running
userspace code), mips64n32 *is* a 32-bit architecture.
We could make that even clearer by having a BR2_KERNEL_ARCH_IS_64, if
there's anything that needs to know at the kernel level the bitness.
But it overall feels incorrect for BR2_MIPS_NABI32 to select
What do you think ?
