[PATCH v3] powerpc/boot: Set LC_ALL=C in wrapper script

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.

This is due to the wrapper script calling 'objdump -p vmlinux' and
looking for 'file format', whereas the output of objdump is:

vmlinux: format de fichier elf32-powerpc

En-tête de programme:
LOAD off 0x00010000 vaddr 0xc0000000 paddr 0x00000000 align 2**16
filesz 0x0069e1d4 memsz 0x006c128c flags rwx
NOTE off 0x0064591c vaddr 0xc063591c paddr 0x0063591c align 2**2
filesz 0x00000054 memsz 0x00000054 flags ---

Add LC_ALL=C at the beginning of the wrapper script in order to get the
output expected by the script:

vmlinux: file format elf32-powerpc

Program Header:
LOAD off 0x00010000 vaddr 0xc0000000 paddr 0x00000000 align 2**16
