[PATCH 7/7] libio: Disable stack protector for tst-fopen-compat with clang

[Adhemerval Zanella]

For aarch64, even with -fno-pie clang 18.1.3 seems to generate
non valid relocations:

tst-fopen-compat.o(.text+0xc): unresolvable R_AARCH64_ADR_PREL_PG_HI21 relocation against symbol `__stack_chk_guard@@GLIBC_2.17'

Disable stack protection in this case.
