Yes, log messages from different files are interleaved based on their timestamps.
Of course, I could redirect the adb logcat output to a file and point this at that, but it'd be nice to have the sugar to not have to explicitly wrap the process.
make |& lnav
The '-t' option will prepend timestamps to the lines that are coming in on stdin so that it will be treated as a log file. The '-w <file>' option will write the stdin data to a file if you want to look at it later: make |& lnav -t -w /tmp/make.out
Is that what you're asking about?
