I think you're still missing what I'm saying.  There should not be a
file that lists fragments.  Outside of documentation, at least.  I was
saying csv above because it would make sense to do something like:
./tools/buildman/buildman --add-fragments=64bit,vpl sandbox
And that would eventually do:
make sandbox_config 64bit.config vpl.config
Which has the standard Kconfig merging of configs/sandbox_defconfig
boards/sandbox/64bit.config (replaces sandbox64_defconfig) and
boards/sandbox/vpl.config
And passing multiple files with a comma seems easiest.
