This does not seems to be directly related to the lttng-modules project.
This errors seems to arise because of the compiler you are using to compile
lttng-modules (kernel modules). The RETPOLINE check is part of the kernel build
system, not directly lttng-modules.
I would recommend that you take a look at the /proc/version file and the
compiler that was used to compile your kernel.
Also note that EfficiOS  provide commercial support if you ever need more
