Some people are familiar with "make rv32_defconfig". There has a
32-bit.config fragment config in arch/riscv/configs/.

I've tested with:

make ARCH=riscv CROSS_COMPILE=riscv32-buildroot-linux-gnu-
EXTRA_CFLAGS+=-g O=../build-rv32/ defconfig 32-bit.config

The above is tested Okay, do you mean we should delete rv32_defconfig?
I think it's another topic, I just want them the same in "compat"
patchset.
