build fails in systemd-sonic-generator when SONIC_PROFILING_ON = y

[Raphael Tryster IL]

I get the following build failure, even from a clean clone, and the cause seems to be that it happens if I uncomment this line in rules/config:

SONIC_PROFILING_ON = y

Is the fix or a workaround known?  Here is the error output from build:

Update: Fixing the changelog file(1 space at start of line, 2 spaces before day) eliminates some, but not all, of the errors, and the build still fails.
