linux-imx (2.6.35.3): perf tools: Fix build against newer glibc

Upstream glibc commit 295e904 added a definition for __attribute_const__
to cdefs.h.  This causes the following error when building perf:

util/include/linux/compiler.h:8:0: error: "__attribute_const__"
redefined [-Werror] /usr/include/sys/cdefs.h:226:0: note: this is the
location of the previous definition

Wrap __attribute_const__ in #ifndef as done for __always_inline.
