Manuel Traut c04e32e911 scripts/decode_stacktrace.sh: prefix addr2line with $CROSS_COMPILE
At least for ARM64 kernels compiled with the crosstoolchain from
Debian/stretch or with the toolchain from kernel.org the line number is
not decoded correctly by 'decode_stacktrace.sh':

  $ echo "[  136.513051]  f1+0x0/0xc [kcrash]" | \
    CROSS_COMPILE=/opt/gcc-8.1.0-nolibc/aarch64-linux/bin/aarch64-linux- \
   ./scripts/decode_stacktrace.sh /scratch/linux-arm64/vmlinux \
                                  /scratch/linux-arm64 \
                                  /nfs/debian/lib/modules/4.20.0-devel
  [  136.513051] f1 (/linux/drivers/staging/kcrash/kcrash.c:68) kcrash

If addr2line from the toolchain is used the decoded line number is correct:

  [  136.513051] f1 (/linux/drivers/staging/kcrash/kcrash.c:57) kcrash
