[PATCH 1/1] tools/perf: add missing include debug.h for arm/arm64

[Fathi Boudra]

Fix perf build failure on arm/arm64 architectures introduced by 
commit 84f5d36f4 (move pr_* debug macros into debug object):

 arch/arm/util/unwind-libunwind.c: In function 'libunwind__arch_reg_id':
 arch/arm/util/unwind-libunwind.c:43:3: error: implicit declaration
 of function 'pr_err' [-Werror=implicit-function-declaration]
   pr_err("unwind: invalid reg id %d\n", regnum);
   ^
 arch/arm/util/unwind-libunwind.c:43:3: error: nested extern declaration
 of 'pr_err' [-Werror=nested-externs]
 cc1: all warnings being treated as errors
 make[2]: *** [arch/arm/util/unwind-libunwind.o] Error 1
 arch/arm/tests/dwarf-unwind.c: In function 'sample_ustack':
 arch/arm/tests/dwarf-unwind.c:20:3: error: implicit declaration
 of function 'pr_debug' [-Werror=implicit-function-declaration]
   pr_debug("failed to allocate sample uregs data\n");
   ^
 arch/arm/tests/dwarf-unwind.c:20:3: error: nested extern declaration
 of 'pr_debug' [-Werror=nested-externs]
