This was due to commit 57fc920 ("Socket: Created control socket & pid file
directories.").

This happened because this commit introduced the usage of
nxt_fs_mkdir_parent() in core code which uses nxt_fs_mkdir(), both of
these are defined in src/nxt_fs.c. It turns out however that this file
doesn't get built on MacOS (or any system that isn't Linux or that
lacks a FreeBSD compatible nmount(2) system call) due to the following

In auto/sources we have

if [ $NXT_HAVE_ROOTFS = YES ]; then
NXT_LIB_SRCS="$NXT_LIB_SRCS src/nxt_fs.c"
fi

NXT_HAVE_ROOTFS is set in auto/isolation

If [ $NXT_HAVE_MOUNT = YES -a $NXT_HAVE_UNMOUNT = YES ]; then
NXT_HAVE_ROOTFS=YES

cat << END >> $NXT_AUTO_CONFIG_H
#ifndef NXT_HAVE_ISOLATION_ROOTFS
#define NXT_HAVE_ISOLATION_ROOTFS 1
#endif
END

fi

While we do have a check for a generic umount(2) which is found on
MacOS, for mount(2) we currently only check for the Linux mount(2) and
FreeBSD nmount(2) system calls. So NXT_HAVE_ROOTFS is set to NO on MacOS
and we don't build src/nxt_fs.c

This fixes the immediate build issue by taking the mount/umount OS
support out of nxt_fs.c into a new nxt_fs_mount.c file which is guarded
by the above while we now build nxt_fs.c unconditionally.

This should fix the build on any _supported_ system.
