[PATCH 5.10 105/129] powerpc/perf: Fix 32bit compile

From: Alexey Kardashevskiy <aik@ozlabs.ru>

[ Upstream commit bb82c574691daf8f7fa9a160264d15c5804cb769 ]

The "read_bhrb" global symbol is only called under CONFIG_PPC64 of
arch/powerpc/perf/core-book3s.c but it is compiled for both 32 and 64 bit
anyway (and LLVM fails to link this on 32bit).

This fixes it by moving bhrb.o to obj64 targets.
