Tried reproducing the issue of sysdig build failure on ppc64el. On
checking the logs minutely, got to know that the issue is due to use of
luaL_setfuncs().
The error was
chisel.cpp:985:9: error: ‘luaL_setfuncs’ was not declared in this scope
This happens because libluajit-5.1-dev does not support ppc64el. As a
result, the current Build-Depends fallback to liblua5.1-0-dev and still
causes incompatibility, since luaL_setfuncs is only available in Lua ≥5.2.
I propose replacing the conditional dependency with a direct one on
liblua5.3-dev, which provides full support for ppc64el and the required API.
I have also tested cross-building sysdig for other architectures
(including amd64, arm64, armel, armhf, mips64el, riscv64 and s390x)
using sbuild, and all of them successfully build with liblua5.3-dev
instead of libluajit-5.1-dev. This suggests that the switch does not
break existing builds and improves compatibility for architectures like
ppc64el that are not supported by LuaJIT. I have attached the patch in
this mail.

Subject: [PATCH] Replace libluajit-5.1-dev with liblua5.3-dev in Build-Depends
to fix the build in ppc64el.
