Hi,

rv32 uclibc toolchain is based on gcc12.2, while rv64 uclibc is based on
gcc13.2

I built them with the mainline buildroot, and rv32 toolchain was built
a year ago, I forget whether there was patches applied. I may apply
patches from your mini-rv32ima repo. The rv64 toolchain was built a
month ago, no patch is applied.

Thanks
