The pipeline will return the status of 'tee' which is almost always 0.
The exit status of the build script is ignored.
A simple fix is store the status in a file and refer to that afterwards.
Another fix uses a separate file descriptor to pass through the status,
like
{ st=$(
{
{ ./kernel-toolchain.sh 2>&1 3>&- 4>&-; echo $? >&3; } | tee logfile >&4
} 3>&1)
} 4>&1
but this is fairly complicated.
The issue can be sidestepped entirely by sending the output to a file
only; a developer can use tail -f to follow the build if necessary.
