musl does not implement GNU extention of strerror_r but XSI compliant
version, therefore add it via a packageconfig to set right variables
during configure to cache the value.
configure detection logic depends on runtime test which will always be
wrong on cross compiles therefore backport a patch to make it possible
to cache the needed configure variable.
