Subject: [PATCH v2 3/3] kbuild: package: add -e and -u options to some shell scripts
Set -e to make these scripts fail on the first error.
Set -u because these scripts are invoked by Makefile, and do not work
properly without necessary variables defined.
I tweaked mkdebian to cope with optional environment variables.
Remove the explicit "test -n ..." from install-extmod-build.
Both options are described in POSIX. [1]
