Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.

timeout previously collected only one child status with wait(2). If this
was one of the grandchildren timeout would return to sigsuspend and wait
until the timeout expired. Instead, loop for all children.

When not using the --foreground option timeout(1) is supported to signal all
command children hierarchy, timeout(1) now acquire the reaper to ensure this
really happens and no children process can escaper from timeout(1) control
According to the coreutils regression testsuite for timeout(1)
It is expect to exit with a status being:
125 in case an invalid duration or signal is passed in arguments
126 in case an invalid command is passed in arguments
127 in case the command passed in arguments does not exists.
While here document this behaviour in the man page
Document the exit values and the duration format
Improve wording

it fully passes the GNU timeout regression tests, it is written in a mostly
