syscall: call f?statfs64 on GNU/Linux

    We unconditionally set _FILE_OFFSET_BITS to 64 in configure.ac, so we
    should unconditionally call the statfs64 and fstatfs64 functions.
    These functions should be available on all versions of GNU/Linux since 2.6.
    On 64-bit systems they are aliased to statfs/fstatfs, and on 32-bit
    systems they use the 64-bit data structures.

runtime: don't use runtime_lock in __go_get_backtrace_state

    If getSiginfo does not know how to determine the PC, it will call
    runtime_callers. That can happen in a thread that was started by
    non-Go code, in which case the TLS variable g will not be set, in
    which case runtime_lock will crash.

    Avoid the problem by using atomic operations for the lock. This is OK
    since creating a backtrace state is fast and never blocks.

    The test case is TestCgoExternalThreadSIGPROF in the runtime package
    on a system that getSiginfo doesn't handle specially.
