device/testing/linux-*: get building again (MR 1684)
Mostly the GCC10 yylloc failure was seen but several others have been
observed:

* wireguard script was silently failing
* several gcc10 x86 errors
* a checksum from kernel.org has changed

Now we have 3 different gcc10 yylloc patches:

gcc10-extern_YYLOC_global_declaration.patch:
    Linux < 4.2

linux4.2-gcc10-extern_YYLOC_global_declaration.patch:
    Linux 4.2+

linux4.17-gcc10-extern_YYLOC_global_declaration.patch:
    Linux 4.17+

Subject: [PATCH] x86/boot/compressed: Don't declare __force_order in
kaslr_64.c
GCC 10 changed the default to -fno-common, which leads to
LD arch/x86/boot/compressed/vmlinux
ld: arch/x86/boot/compressed/pgtable_64.o:(.bss+0x0): multiple definition of `__force_order'; \
arch/x86/boot/compressed/kaslr_64.o:(.bss+0x0): first defined here
make[2]: *** [arch/x86/boot/compressed/Makefile:119: arch/x86/boot/compressed/vmlinux] Error 1
Since __force_order is already provided in pgtable_64.c, there is no
need to declare __force_order in kaslr_64.c.
