Please describe the actual problem in the changelog. I guess it's
because of the 'ERR' trap?

Why not use 'cleanup' directly as a handler?

Indeed:
- ERR is specific to bash
- signal names in a trap built-in instruction should be without the SIG prefix
Shall I repost a v2 with the above lines?

Sorry if I wasn't clear. The changelog should contain the actual error
message or description of wrong behavior when ran under dash.

While building linux with dash shell:
LINK vmlinux
trap: SIGHUP: bad trap
/src/linux-4.0/Makefile:933: recipe for target 'vmlinux' failed
make[1]: *** [vmlinux] Error 1
