I've noticed that smart-autogen.sh has "set -ux" and it is invoked from GUB.
If I understand correctly, "set -u" and "set -x" etc. do not carry over
into child processes.

However, at least in your log file,
"set -x" seems to be carried over to the child process.

In my log file, "set -x" does not seem to be carried over to the child process.
Only smart-autogen.sh is setted tracemode.
autogen.sh and autoconf are not setted trace mode.

Perhaps, also "set -u" is carried over in your environment
and it is not carried over in my environment.

I have no idea.
But, in CentOS, /bin/sh is symbolic link to bash,
whereas in Ubuntu, /bin/sh is dash.
I think that this difference is influenced.
