Fixes a buildroot build error with ffmpeg
In file included from /home/bernd/buildroot/output/host/aarch64-buildroot-linux-uclibc/sysroot/usr/include/signal.h:329:0, from fftools/ffmpeg.h:26, from fftools/ffmpeg_opt.c:23: /home/bernd/buildroot/output/host/aarch64-buildroot-linux-uclibc/sysroot/usr/include/sys/ucontext.h:52:16: error: field 'uc_mcontext' has incomplete type mcontext_t uc_mcontext; ^~~~~~~~~~~
using this defconfig:
BR2_aarch64=y BR2_PACKAGE_FFMPEG=y
sys/ucontext.h for other archs already include bits/sigcontext.h, on aarch64 this is needed as well.
