Subject: [PATCH] Printf test suite fails on systems with musl libc because
tests for "%m" and "%M" formats expect "Input/output error" message but musl
returns "I/O error". Proposed change compares the printf output with string
returned from strerror function for EIO constant.

Minor change from committer.
