perf build: Error if jevents won't work and NO_JEVENTS=1 isn't set
Rather than disabling jevents if a sufficient python isn't present
error in the build. This avoids the build progressing but the binary
being degraded. The build can still succeed by specifying NO_JEVENTS=1
to the build and this is conveyed in the error message.
