Subject: [PATCH] Enable THREADS_PREFER_PTHREAD_FLAG

Fixes build failures on risv64

Taken from https://trac.webkit.org/changeset/231843/webkit

 Enable THREADS_PREFER_PTHREAD_FLAG. This uses -pthread instead of
-lpthread, fixing the 64-bit RISC-V build of the GTK+ port due to
missing atomic primitives.

Upstream-Status: Submitted [https://trac.webkit.org/changeset/231843/webkit]
