Bug description:
crash 7.2.6-1ubuntu1 now fails on arm64 w/ an Illegal instruction:
$ sudo crash -st /usr/lib/debug/boot/vmlinux-$(uname -r) /proc/kcore
Illegal instruction
The previous version of crash was 7.2.6-1build1. While there are no
differences in the source code (just an autopkgtest update), it did
not hit this:
$ sudo crash -st /usr/lib/debug/boot/vmlinux-$(uname -r) /proc/kcore

I've verified that the significant difference is with the version of
binutils used to build crash.
2.33.50.20200107-1ubuntu1 - Illegal instruction
2.33.1-6ubuntu3 - OK
2.32.51.20190905-0ubuntu1 - OK
