Hi,
Thank you for this great info.
I know this is old repo. But for others who seek this, there is one think that needs to be done before building selinux. In this command gcc -c callbacks.c check_context.c freecon.c init.c label.c label_file.c label_android_property.c -I../include -I../../core/include -DDARWIN -DHOST, remove -DDARWIN flag if you are building this in linux machine. This is the reason for the above error, init.c: In function ‘init_selinuxmnt’: init.c:31:16: error: storage size of ‘sfbuf’ isn’t known struct statfs sfbuf;.

Thanks! You made it very easy to build make_ext4fs on OS X.
