You forgot to propagate this dependency to the sysdig package, which
selects luajit, so I've done that an applied.

Technically speaking, it is possible to build luajit in
BR2_STATIC_LIBS=y configuration, by setting LJ_TARGET_DLOPEN to 0 in
src/lj_arch.h, but then you cannot load any C module, which makes
LuaJIT maybe a little bit useless. If anyone is interested, they can
always work on making this change.

Thanks!
