btrfs-progs: get C=1 sparse checking working again
There were a few problems that were breaking sparse checking: - We were defining CHECK_ENDIAN late in the environment, after linux/fs.h has been included which defines __force and __bitwise in confusing ways that conflict with ours. Define it up with __CHECKER__ so that linux/fs.h and our copy are acting on the same input. - We had manually set a few of gcc's internal defines to give to sparse. It's easier to just ask gcc for all the defines it sets and hand those to sparse. - We weren't passing the same *FLAGS to sparse as we were to CC. - glibc has so many errors with FORTIFY turned on that sparse gives up and doesn't show us any errors from our code. It's a questionable hack to always turn on FORTIFY ourselves, so we'll just not do that when building with sparse. And add a nice '[SP]' quiet output line for sparse checks.
