Subject: [Buildroot] Qt5 fails to compile with gcc 6.1.0

Same environment of the previous email. Qt5 fails with this error:

which means: "file or directory not found".
stdlib.h is in sysroot/usr/include:

> /host/usr/arm-buildroot-linux-gnueabihf/sysroot/usr/include/stdlib.h

It seems the same behavior reported here:

Right now I'm rebuilding once again with an older version of gcc, hoping 
this won't trigger the kernel-panic as in gcc 4.8.
