btrfs: fix build to link against libgcc_s so that pthread_cancel is linked

Browse Source 
Currently, the command btrfs scrub start <filesystem> attempts to invoke the pthread_cancel
routine and ends with an error melibgcc_sssage about it being missing. This prevents btrfs
scrub status from maintaining proper statistics about the running scrub.

Close #1127.
