Description Lauri Kasanen 2013-04-02 15:51:15 UTC 
With busybox ash as /bin/sh, the kernel build (3.8.4) fails in scripts/link-vmlinux.sh with:

scripts/link-vmlinux.sh: trap: line 105: ERR: invalid signal specification

According to Denys Vlasenko, trapping ERR is not defined in POSIX, so it seems to be a bashism:

Regression, since the linking was done in a Makefile before 3.5.
