[Buildroot] [PATCH v2 15/17] openal: add missing BR2_TOOLCHAIN_HAS_SYNC_4 dependency

["André Hentschel" <nerv@dawncrow.de>]

Hi Thomas,

Isn't openal looking for the atomic functions and not for the sync ones?
As seen in the URL you provided:

libopenal.so.1.17.1: undefined reference to `__atomic_fetch_sub_4'
libopenal.so.1.17.1: undefined reference to `__atomic_compare_exchange_4'
libopenal.so.1.17.1: undefined reference to `__atomic_fetch_add_4'
