Hi, @yavtuk. 

Thanks for highlighting this. 

Just a minor addition. The hugify test for AArch64 was slightly modified. That is why initially I kept it separated.

Regarding %cflags, If remove it what we should do with the following:

`--target=aarch64-unknown-linux-gnu -fPIE -fuse-ld=lld -Wl,--unresolved-symbols=ignore-all -pie`
 
maybe we need to exclude -fPIE you mean for no-pie test? 

Though, few tests were added as well: 
- section-order.test
- user-func-reorder.c

Personally, I would prefer to have required flags specified explicitly in test file.  

If you have some ideas about other tests that could benefit AArch64 from X86 set, let me know, I will try to check them.
