+Subject: [PATCH] qtbase: Add OE clang specific mkspecs
+
+We can not piggy back clang anymore on existing
+OE mkspecs since starting 5.9 the configure is
+asking compiler for include paths and it needs to
+know if platform is clang-linux or g++-linux
+
+Fixes:
+ERROR: failed to parse default search paths from compiler output

+Subject: [PATCH] linux-clang: Invert conditional for defining QT_SOCKLEN_T
+
+This helps to make sure that QT_SOCKLEN_T is defined to be 'int'
+only when its glibc < 2 and not for other libcswhich may define
+it as per standards but are not glibc, e.g. musl
