[meta-freescale] [meta-fsl-arm][PATCH 1/2] linux-imx (2.6.35.3): Fix perf build due new Linux headers use

[Otavio Salvador]

As Yocto now use a newer Linux headers package we end having a build
failure in perf as 'stddef.h' has changed and does not provide NULL
definiton anymore. To workaround it we add the srcdir onto search path
for include files, before sysroot one.
