[PATCH v3 09/23] buildman: Drop the -a option

Simon Glass sjg at chromium.org
Wed Mar 18 16:42:47 CET 2020

There is no point in setting the ARCH environment variable since the
U-Boot build system no-longer uses it.

It seems safe to drop this feature since it was only recently added.

Signed-off-by: Simon Glass <sjg at chromium.org>

Changes in v3:
- Drop mention of -a in the README also

Changes in v2:
- Add a new patch to drop the -a option
