From b520d58d00b7ed6c5cc9bc97c62f07e09f4f49ad Mon Sep 17 00:00:00 2001

Subject: [PATCH] regressions/common: rename gettid wrapper to common_gettid.
glibc-2.30 added a wrapper to gettid (https://lwn.net/Articles/795127/).
gettid will clash with the glibc-provided symbol. Remove the
macro and instead move to a dedicated namespace.
We go this route to avoid introducing unnecessary complexity to
build.
Fixes #147
