+Subject: [PATCH] Build debug version of bjam
+
+bjam is stripped by default, this causes QA warning while stripping it
+from do_populate_sysroot():
+
+  WARNING: File '.../tmp/sysroots/x86_64-linux/usr/bin/bjam' \
+    from bjam-native was already stripped, \
+    this will prevent future debugging!
+
+The JAM scripts allow to build unstripped version with '--debug'. Just
+build and install the bjam.debug to stop bjam from being stripped in
+compile step.

+Subject: [PATCH] build.sh: use -DNDEBUG also in debug builds
+
+Without it, there is a significant performance regression
+when running 'bjam install'.
