boost: update to 1.71.0

Some notes:
- bjam bootstrap scripts were changed, and the patch for that had to be
  adjusted. tools/build/src/engine/build.sh now supports an --debug option
  which the bjam-native recipe can use to get the debug build of b2.
- a related patch was added to address a speed regression with the debug
  version of bjam
- gcc.jam patch had to be refreshed because boost added more "cpu-flags"
  lines.
- since 1.70.0, boost includes new cmake config files which are packaged
  in ${PN}-dev now so they make it into the SDK. (although 1.71.0 is needed
  to fix some bugs in them)

+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.
