[AArch64] Use __getauxval instead of getauxval in LSE detection code in libgcc
This version of the fix uses __getauxval instead of getauxval.
The whole thing is guarded simply on __gnu_linux__.
__getauxval was introduced in 2.16 but the aarch64 port was added in 2.17 so in practice I expect all aarch64 glibcs to support __getauxval.
Bootstrapped and tested on aarch64-none-linux-gnu.
Also tested on aarch64-none-elf.

* config/aarch64/lse-init.c (init_have_lse_atomics): Use __getauxval
instead of getauxval.
(AT_HWCAP): Define.
(HWCAP_ATOMICS): Define.
Guard detection on __gnu_linux__.
