Only build and use the compat.c bsd_setenv/bsd_putenv/bsd_unsetenv on systems

that don't provide the POSIX setenv().

This fixes building plugins that link to compat.c on OS X (shared libraries on
OS X don't have direct access to environ).  It also reduces the binary size on
platforms which provide setenv(), which these days is most of them.
