Not exactly: -l does list the failing boards, but it does so as
they are found, mixing the warning and error cases. MAKEALL lists them
at the end, in a summary, where all boards with warning are listed
together and so are all boards with errors. I don't mind getting the
list displayed before the end, for instance each time a new board
fails, but I really would like it to be grouped by failure type
(warning or error) and ideally, sorted in alphabetical board name order.

Also, -l apparently does not prevent all notes, warnings and error
diagnostics from being emitted by the compiler during builds.

Plus, with -l, there seems to be a weird bug whereby a single board gets
listed a bazillion times for a warning.

To make things easier, I have pushed the commit I am using with
buildman as branch "buildman_test" on u-boot-arm, and here is the
command line I use, without -l:

	tools/buildman/buildman -o build -k odroid apalis_t30
	tricorder_flash tricorder edminiv2 wireless_space

And with -l

	tools/buildman/buildman -o build -k odroid apalis_t30
	tricorder_flash tricorder edminiv2 wireless_space -l

The first four boards have warnings or errors (the last two ones are
just added as known guild build cases) with gcc version 4.8.2
(Ubuntu/Linaro 4.8.2-16ubuntu4).

Again, if this is not possible, I am willing to contribute a patch to
get it done.
