precompiled code from calls.lua broken on big endian systems

[Dan Horák <dan@...>]

Hello,

the calls test fails in Lua 5.4 on big endian platforms (ppc64, s390x),
please see https://bugzilla.redhat.com/show_bug.cgi?id=2226537 for the
original report. I suppose it is because the precompiled code added in
https://github.com/lua/lua/commit/ab859fe59b464a038a45552921cb2b23892343af
is from a little endian system (eg. x86) and is platform specific, thus
it won't load correctly on a big endian system. Is there a way how to
fix it?


	Thanks,

		Dan
