Glibc >=2.32 exposes a gettid() which clashes with libcutils thread.h, so add a check to not expose it if building against newer glibc (ChromiumOS will still use glibc 2.27 besides 2.32). Bug: https://bugs.chromium.org/p/chromium/issues/detail?id=1182060 Test: Builds without errors on both glibc 2.32 and 2.27. Change-Id: Ib71fa1bc9fa185e3668002407dbed05a80c87740
