+Subject: [PATCH] meson: Use PKG_CONFIG_SYSROOT_DIR when using pkg-config
+
+OE cross-builds and absolute paths found by pkg-config points to
+non-sysroot'ed locations which are not correct as they point into native
+sysroot from build machine which is incorrect.
+
+Upstream-Status: Inappropriate [OE-specific]
