[PATCH] perf record: Conditionally define CLOCK_MONOTONIC_RAW for older OSes

From: Yunlong Song
Date: Wed Apr 08 2015 - 00:00:10 EST

Commit 31a9883106cc ("perf record: Add clockid parameter") used
CLOCK_MONOTONIC_RAW in the struct clockid_map clockids[], but the
CLOCK_MONOTONIC_RAW macro is not defined in older releases (e.g., SLES
11 SP2), thus there is a building error when making perf:

builtin-record.c:738: error: âCLOCK_MONOTONIC_RAWâ undeclared here (not in a function)
make[2]: *** [builtin-record.o] Error 1
make[2]: *** Waiting for unfinished jobs....
LD bench/perf-in.o
LD tests/perf-in.o
make[1]: *** [perf-in.o] Error 2
make: *** [all] Error 2

So define this macro if it is not defined.
