+Subject: [PATCH] lttng-ust-elf.c: define NT_GNU_BUILD_ID if not defined
+
+On uClibc, NT_GNU_BUILD_ID is not defined, so we define it
+manually in this case.

+Subject: [PATCH] doc/examples/Makefile.am: define C and C++ compilers for
+ CMake
+
+This prevents build failures when cross-compiling.
+
+If we don't define the compiler, it will use the one from the host
+machine. For instance "/usr/bin/c++", which is incorrect.
+
+The failure looks like this:
