I don't know why.

All I know is that when building SILE I got the message

/usr/bin/ld: //usr/local/lib/liblua.a(lapi.o): relocation R_X86_64_32
against `luaO_nilobject_' can not be used when making a shared object;
recompile with -fPIC

and after I rebuilt Lua with -fPIC, that message did not appear again.

Maybe it is because SILE embeds liblua rather than that the Lua executable
loads a C module.
