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. 2020-05-06 Kyrylo Tkachov <kyrylo.tkachov@arm.com> * 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__.
