When writing a test for fusectl, I referred to this Makefile as a reference for creating a FUSE daemon in the selftests. While doing so, I noticed that there is a minor issue in the Makefile.

The fuse_mnt.c file is not actually compiled into fuse_mnt.o, and the code setting CFLAGS for it never takes effect. The reason fuse_mnt compiles successfully is because CFLAGS is set at the very beginning of the file.
