its possible that we have bugs in 1.7 and it was long time ago, we did
fix non-glibc builds in later releases so I am not
surprised that you get better results with newer releases. Btw. uclibc
has been deprecated in 2.1 and will be removed from 2.2 release, so
plan to move to musl if you need smaller libc
