[PATCH][testsuite][aarch64]: Fix gcc.target/aarch64/auto-init-* tests.

[Qing Zhao <qing.zhao@oracle.com>]

Hi, 

This is the patch to fix gcc.target/aarch64/auto-init-* tests.

I have tested the change on aarch64-linux with 

make check-gcc RUNTESTFLAGS='--target_board=unix\{-mabi=lp64,-mabi=ilp32,-mabi=lp64/-fstack-clash-protection/-fstack-protector-all,-mabi=ilp32/-fstack-clash-protection/-fstack-protector-all,-mabi=lp64/-march=armv8-a,-mabi=ilp32/-march=armv8.2-a,-mabi=lp64/-march=armv8.4-a,-mabi=ilp32/-march=armv8.6-a,-mabi=lp64/-march=armv8-r\} aarch64.exp=auto-init*'

Everything works fine.

Okay for commit?

Thanks.

Qing
