[PATCH] man/man3/pthread_attr_init.3: Replace errc

[dave@treblig.org]

From: "Dr. David Alan Gilbert" <dave@treblig.org>

The pthread_attr_init.3 example uses 'errc' to exit on an error
printing the error code.  However, 'errc' is a BSDism that Linux
doesn't (and has never?) have.

Replace it by 'errx' with a strerror() call.
