Thanks for the suggestion.
Too bad we don't have in-house expert in klibc and musl port. 

Hi HPA,
I knew you are the developer of klibc. Do you have any documentation to
port a new architecture and also how to replace glibc with klibc in
build?

By the way, klibc or musl is easier to port?
Thanks.
