Attempting to build the perf tool for an arm64 target results in the
following failure:
arch/arm64/util/unwind-libunwind.c: In function 'libunwind__arch_reg_id':
arch/arm64/util/unwind-libunwind.c:77:3: error: implicit declaration of function 'pr_err'
pr_err("unwind: invalid reg id %d\n", regnum);
^
arch/arm64/util/unwind-libunwind.c:77:3: error: nested extern declaration of 'pr_err'
This is due to commit 84f5d36f48 ("perf tools: Move pr_* debug macros
into debug object") moving the pr_* macros into a new header file, but
failing to update architectures other than x86.
This patch adds the missing include, and fixes the build again.
