python3-grpcio: add bbappend
Add bbappend to tweak the LDFLAGS used when building for RISC-V so that libatomic gets linked as is required. See the comment in the .inc file for more information.

+# For some reason the atomics presence test in the grpc build
+# passes on RISC-V even though linking with libatomic is actually
+# needed. There are some mentions on the web of some atomics
+# support incorrectly being in the libc stub on RISC-V, so a
+# fix could be tracking down if that is the case and if it has
+# been fixed in newer libc. Otherwise, the compile test in grpc
+# will need to be changed to some other function that is known to
+# only be in libatomic on RISC-V.
+#
+# The next problem is that setting GRPC_PYTHON_LDFLAGS to any value
+# ends up not adding linking with pthread due to the way the logic
+# is set up, so we need to actually add it explicitly. The upstream
+# recipe seems slightly broken in this respect.
