[FYI][PATCH 1/1] perf tools: Set COMPAT_NEED_REALLOCARRAY for CONFIG_AUXTRACE=1

[Arnaldo Carvalho de Melo]

As it is being used in tools/perf/arch/arm64/util/arm-spe.c and the
COMPAT_NEED_REALLOCARRAY was only being set when CORESIGHT=1 is set.

Fixes: 56c31cdff7c2a640 ("perf arm-spe: Implement find_snapshot callback")
