Actually, both of these are fixed upstream already, but not as isolated commits
I can backport. There is a newer upstream release (v1.42.11) but it doesn't
contain the necessary fixes. It appears that the missing <limits.h> inclusion is
in a file added by patches in openembedded-core.

I shan't attempt the upgrade as there are a lot of patches in openembedded-core
to consider. I will try to make an isolated fix for the build issues with musl
though.
