[PATCH] powerpc: Fix writable sections being moved into the rodata region

[Nicholas Piggin]

.data.rel.ro*  catches .data.rel.root_cpuacct, and the kernel crashes on
a store in css_clear_dir. At least we know read-only data protection is
working...

Fixes: b6adc6d6d3272 ("powerpc/build: move .data.rel.ro, .sdata2 to read-only")
