+Using musl libc the task do_configure fails on powerpc*.
+
+  checking build system type... x86_64-pc-linux-gnu
+  checking host system type... powerpc-oe-linux-musl
+  checking for python3.5... python3.5
+ ...
+  checking for the platform triplet based on compiler characteristics... 
+  powerpc-linux-gnu
+  configure: error: internal configure error for the platform triplet
+
+Fix this by adding the musl triplets.
+Note: uclibc is purposedly not considered (unsupported in oe-core).
