Are you sure it's not supported? Or is it just disabled in your kernel config?
I'm looking at Kconfig and nothing suggests you can't use it on aarch64:
config SYSFS_SYSCALL
bool "Sysfs syscall support" if EXPERT
default y
---help---
sys_sysfs is an obsolete system call no longer supported in libc.
Note that disabling this option is more secure but might break
compatibility with some systems.
If unsure say Y here.
We have "linux_syscall_numbers.h", if you include that and use
ltp_syscall() instead of syscall() you can remove the #ifdef,
as it should TCONF at runtime (in case kernel gives you ENOSYS)

Jan
