I think what you can do is to add rv32_defconfig as a target in
arch/riscv/Makefile the same way as rv32_randconfig, and then
delete the other file, that will keep the existing process working
for any existing users.

Given that there are no specific rv32 SoC implementations supported
by the kernel today (other than SOC_VIRT), the number of users
would be close to zero anyway.
