"<<<" isn't portable shell. Could you try with:
echo ${component} | tr ...
instead?
As it stands, this causes a bootstrap failure with non-bash shells
such as dash, even on non-Loongson targets.
(Part of me wishes that we'd just standardise on bash. But since that
isn't the policy, I sometimes use dash to pick up my own lapses.)
Thanks,
Richard
