+Subject: [PATCH] meson.build: check for pthread.h
+
+Check for pthread.h otherwise the build will fail with some toolchains
+that have libphtread.so but not pthread.h:
+
+Run-time dependency threads found: YES
+
+../src/hb-mutex.hh:53:10: fatal error: pthread.h: No such file or directory
+ #include <pthread.h>
+          ^~~~~~~~~~~
+
+Moreover, fix detection of pthread fallback
+
