Add binutils 2.39 and regenerate patches.
0008-binutils-2.38-vs.-ppc32-linux-kernel.patch is dropped as it has
been applied upstream. Add a milestone for 2.39 which will be handy for
Loongarch.
Binutils now requires bison >= 3.0.4 to build gprofng for x86/aarch64 so
we build our own bison when the host bison does not meet that
requirement (which appears to be the case on macOS).
