Merge remote-tracking branch 'kiszka/jan/fix-samba36-build'

build: Properly set num_build_thread_str in auto mode

samba36: Disable parallel build

mvebu: Add back dhcpv6 server and client

Add patch for building libtirpc with GCC 10, otherwise this can crash build. GCC 10 sets -fno-common to be enabled by default, which is the behavior that caused this issue.
