Благодарю!
Вся моя проблема была в отсутствии 2-ой строки.export LUAJIT_INC=%{_includedir}/luajit-5_1-2.1
export LUAJIT_LIB=%{_libdir}
Видимо если переопределяю LUAJIT_INC то нужно сразу и переопределить LUAJIT_LIB даже если она стандартная.
Луамодуль собрал, буду собирать lua-resty-redis.
P.S. /var/log/nginx/error.log
2024/04/19 11:21:48 [alert] 23985#23985: detected a LuaJIT version which is not OpenResty's; many optimizations will be disabled and performance will be compromised (see https://github.com/openresty/luajit2 for OpenResty's LuaJIT or, even better, consider using the OpenResty releases from https://openresty.org/en/download.html)

Ещё и lua-resty-core нужен.
