By luck since you only circumvented the proper checks, unfortunately.
The variables as defined in the configure script are perfectly ok,
CONFIG_X86_TSC is the right option to set.
The message you got initially told you that a discrepancy between the
CPU selected at kernel level and the user-support has been detected. To
fix this, you need to select a x86 CPU supporting a timestamp counter
when configuring your kernel, since by default, the configure script
assumes --enable-x86-tsc.
In any case, keep in mind that updating the configure script output
(xeno_config.h) by hand is always the wrong way to fix an issue.
