Without this the pgo-related compiler flags are not used in
cross-builds.

+Subject: [PATCH] Use correct CFLAGS for extensions when cross-compiling
+
+Take PY_CFLAGS_NODIST into account, like in native build. This is needed
+in order to to profile-optimized build. Also, pass EXTRA_CFLAGS to
+profile-optimized build.
