Subject: [PATCH] Amend fix for #9 to apply to other Unix systems

At least the musl libc on Linux has the same issue as Mac OS X: the
PTHREAD_RECURSIVE_* static initialiser does not exist.  This is a
documented and purposeful omission:

This commit uses similar logic to the Apple test on other Unixes.
