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.
