+Subject: [PATCH] fix sqlite3 on ppc with clang
+
+The __ppc__ macro is always defined on clang but not gcc, which
+results in sqlite mistakenly thinking that ppc64le with clang
+is big endian.
+
+Also disable some inline assembly stuff on ppc that is never used
+with gcc and probably was never tested with modern machines.
