Subject: signrom.sh: portability fix
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=99772ae20895e9c72e15f8bef89c60fadd7eb0da;p=qemu.git

signrom.sh: portability fix

Attached patch makes signrom.sh working on NetBSD.
The output of the 'od' command leads to a syntax error
which breaks the build.
