OK, lets start.  First, I had to make up a special directory with
symlinks to the various toolchains, in order to get them to work with
buildman, due to the various layouts:

$ ls -l ~/work/u-boot/toolchain-links/
total 4
lrwxrwxrwx 1 trini trini 38 Aug  1 17:09 arc_gnu_4.8-R2_prebuilt_uclibc_be -> /opt/arc_gnu_4.8-R2_prebuilt_uclibc_be
lrwxrwxrwx 1 trini trini 38 Aug  1 17:09 arc_gnu_4.8-R2_prebuilt_uclibc_le -> /opt/arc_gnu_4.8-R2_prebuilt_uclibc_le
lrwxrwxrwx 1 trini trini 24 Aug  1 17:10 bfin-elf -> /opt/uClinux-45/bfin-elf
lrwxrwxrwx 1 trini trini 32 Aug  1 17:09 m68k-linux -> /opt/gcc-4.9.0-nolibc/m68k-linux
lrwxrwxrwx 1 trini trini 34 Aug  1 17:09 microblazeel-xilinx-linux-gnu -> /opt/microblazeel-xilinx-linux-gnu
lrwxrwxrwx 1 trini trini 32 Aug  1 17:09 microblaze-xilinx-linux-gnu -> /opt/microblaze-xilinx-linux-gnu
lrwxrwxrwx 1 trini trini 66 Aug  1 17:15 mips32-linux -> /opt/eldk-5.2.1/mips/sysroots/i686-eldk-linux/usr/bin/mips32-linux
lrwxrwxrwx 1 trini trini 36 Aug  1 17:09 nds32le-linux-glibc-v1f -> /opt/nds32le/nds32le-linux-glibc-v1f
lrwxrwxrwx 1 trini trini 20 Aug  1 17:09 sparc-elf-3.4.4 -> /opt/sparc-elf-3.4.4

I tried a few things but I couldn't get a toolchain section setup that
found all of those.  Second:
(testing the MMC pull request)
$ ./tools/buildman/buildman -b master
'arc|blackfin|m68k|microblaze|nds32|sparc|mips'
No section: 'make-flags'

So it's nice that it spit out a thread per commit, but I really only
care right now if master builds right.  And I've gone blind and can't
find the end result logs of what failed to build (88 failures doesn't
quite match the warning/errors I get for my wrapper around
toolchains+MAKEALL).

I also didn't quite see how to plugin an arm64 toolchain.

Next up, is there some way to have multiple toolchains for an arch
available?  On some compute resources I have at work I throw
arm/eldk4.2, arm/eldk5.2, arm/linaro-2013.03 (since we've pinned to that
for some projects) and some various combos for powerpc as well.  I
didn't see how to do that with buildman aside from different ~/.buildman
files per invocation.

Thanks!
