[ Upstream commit e3f506b78d921e48a00d005bea5c45ec36a99240 ]
'commit b2accfe7ca5b ("powerpc/boot: Check for ld-option support")' suppressed
linker warnings, but the expressed used did not go well with POSIX shell (dash)
resulting with this warning
arch/powerpc/boot/wrapper: 237: [: 0: unexpected operator
ld: warning: arch/powerpc/boot/zImage.epapr has a LOAD segment with RWX permissions
Fix the check to handle the reported warning. Patch also fixes
couple of shellcheck reported errors for the same line.
In arch/powerpc/boot/wrapper line 237:
if [ $(${CROSS}ld -v --no-warn-rwx-segments &>/dev/null; echo $?) -eq 0 ]; then
^-- SC2046 (warning): Quote this to prevent word splitting.
^------^ SC2086 (info): Double quote to prevent globbing and word splitting.
^---------^ SC3020 (warning): In POSIX sh, &> is undefined.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
