direct_syscall is ARM state assembler. If libhugetlbfs is compiled for
the Thumb state it does not currently change execution states when it
calls direct_syscall, leading to unpredictable behaviour.
This patch marks direct_syscall as a FUNC, which enables the ARM/Thumb
state interworking; resulting in a BLX to direct_syscall where
necessary.
