mips: Add -std= flag specified in KBUILD_CFLAGS to vdso CFLAGS
commit 0f4ae7c6ecb89bfda026d210dcf8216fb67d2333 upstream.
GCC 15 changed the default C standard dialect from gnu17 to gnu23,
which should not have impacted the kernel because it explicitly requests
the gnu11 standard in the main Makefile. However, mips/vdso code uses
its own CFLAGS without a '-std=' value, which break with this dialect
change because of the kernel's own definitions of bool, false, and true
conflicting with the C23 reserved keywords.
include/linux/stddef.h:11:9: error: cannot use keyword 'false' as enumeration constant
11 | false = 0,
| ^~~~~
include/linux/stddef.h:11:9: note: 'false' is a keyword with '-std=c23' onwards
include/linux/types.h:35:33: error: 'bool' cannot be defined via 'typedef'
35 | typedef _Bool bool;
| ^~~~
include/linux/types.h:35:33: note: 'bool' is a keyword with '-std=c23' onwards
Add -std as specified in KBUILD_CFLAGS to the decompressor and purgatory
CFLAGS to eliminate these errors and make the C standard version of these
areas match the rest of the kernel.
