perf tools: fix ALIGN redefinition in system headers
On some systems (e.g. Android), ALIGN is defined in system headers as
ALIGN(p). The definition of ALIGN used in perf takes 2 parameters:
ALIGN(x,a). This leads to redefinition conflicts.
Redefinition error on Android:
In file included from util/include/linux/list.h:1:0,
from util/callchain.h:5,
from util/hist.h:6,
from util/session.h:4,
from util/build-id.h:4,
from util/annotate.c:11:
util/include/linux/kernel.h:11:0: error: "ALIGN" redefined [-Werror]
bionic/libc/include/sys/param.h:38:0: note: this is the location of
the previous definition
Conflics with system defined ALIGN in Android:
util/event.c: In function 'perf_event__synthesize_comm':
util/event.c:115:32: error: macro "ALIGN" passed 2 arguments, but takes just 1
util/event.c:115:9: error: 'ALIGN' undeclared (first use in this function)
util/event.c:115:9: note: each undeclared identifier is reported only once for
each function it appears in
In order to avoid this redefinition, ALIGN is renamed to PERF_ALIGN.
