[PATCH v3] powerpc/boot: Fix build with gcc 15

[Michal Suchanek]

Similar to x86 the ppc boot code does not build with GCC 15.

Copy the fix from
commit ee2ab467bddf ("x86/boot: Use '-std=gnu11' to fix build with GCC 15")

v2: Move the fix outside of ifdef to apply to all subarchitectures
v3: Change BOOTCFLAGS rather than BOOTTARGETFLAGS
