From: Alice Frosi <al...@linux.vnet.ibm.com>
In alpine docker image the qemu-system-s390x build is broken and
it throws this error:
qemu-system-s390x: Initialization of device s390-ipl failed: could not
load bootloader 's390-ccw.img'
The grep command of busybox uses regex. This fails on binary data
(e.g. stops on every \0), so it does not identify the string
BiGeNdIaN in the test case big/little. Therefore, it assumes
that the architecture is little endian.
This fix solves the grep problem by printing the content of
TMPO with strings

[some changes to patch description, add -a option to strings]
