+Subject: [PATCH] meson.build: explicitly check for pthread support
+
+Tested using buildroot. The br-arm-full-nothread fails
+because meson assumes thread support when cross-compiling.
+
+Dependency threads found: YES unknown (cached)
+Has header "pthread.h" : NO
+
+Upstream: https://gitlab.freedesktop.org/fontconfig/fontconfig/-/commit/aad470dad519b6fe3459023b82941b4414b71313
