Later below expand the failing and previoly good commands, one
option per line. The summary of the distinction in content is
a one line difference, the working example ( -r335773 )had the
option:

-isystem =
/workspace/obj/workspace/src/amd64.amd64/obj-lib32/tmp/usr/include

but the failing one did not. Working ( -r335773 ) is shown first.
