Thanks for the patch.

Now i have manually tested LTP syscalls and confirms,
fcntl35 and fcntl35_64 pass on qemu_x86_64, (arm64) Hikey, Juno and (arm32) x15.

fcntl35 and fcntl35_64 will be unskipped from now on.

select04 failed on (slow) qemu_arm only and PASS on real hardware of
arm32 x15, arm64 Juno and x86_64.
