Subject: ARM: fix perf build with uclibc toolchains
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0ac8e58f3818795d02ac309bd57b4d93ec283a77;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

ARM: fix perf build with uclibc toolchains

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'.
