mainlining shenanigans

While trying to build a simple Image for ACADIA platform, I got the following error: WRAP arch/powerpc/boot/simpleImage.acadia INFO: Uncompressed kernel (size 0x6ae7d0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) powerpc64-linux-gnu-ld : mode d'émulation non reconnu : -T Émulations prises en charge : elf64ppc elf32ppc elf32ppclinux elf32ppcsim elf64lppc elf32lppc elf32lppclinux elf32lppcsim make[1]: *** [arch/powerpc/boot/Makefile:424 : arch/powerpc/boot/simpleImage.acadia] Erreur 1 make: *** [arch/powerpc/Makefile:285 : simpleImage.acadia] Erreur 2 Trying again with V=1 shows the following command powerpc64-linux-gnu-ld -m -T arch/powerpc/boot/zImage.lds -Ttext 0x700000 --no-dynamic-linker -o arch/powerpc/boot/simpleImage.acadia -Map wrapper.map arch/powerpc/boot/fixed-head.o arch/powerpc/boot/simpleboot.o ./zImage.3278022.o arch/powerpc/boot/wrapper.a The argument of '-m' is missing.

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.
