Subject: [PATCH] perf: fix build for PowerPC with uclibc toolchains

From: Florian Fainelli <[email-masked]>
Date: Tue, 23 Aug 2011 14:20:08 +0200

libio.h is not provided by uClibc, in order to be able to test the
definition of __UCLIBC__ we need to include stdlib.h, which also
includes stddef.h, providing the definition of 'NULL'.
