When I built buildroot for k210, I encountered the error message below. Please help! Thanks

This looks like "make" is crashing... Not sure what is going on here. This project does not change make itself. There may be a problem with some of the tools in the toolchain causing this.

I will be updating this project very soon since the final patches needed for k210 were added to kernel 5.8. I will update once 5.8.0-rc1 kernel is out next week.

I found that I used "make" in the riscv64-unknown-elf- cross-compile chain, instead of the "make" in Ubuntu. Thanks Damien for the help !

@damien-lemoal thanks, I look forward to 5.8 :)
