Compiling liblegato for Raspi 3

[udi-hakim]

When using gcc-linaro-arm-linux-gnueabihf-raspbian-x64 as the toolchain, the file epoll.h in \arm-linux-gnueabihf\libc\usr\include\arm-linux-gnueabihf\sys does no support EPOLLWAKEUP.

/home/user/projects/workspace/legato/framework/liblegato/linux/fdMonitor.c:57:12: note: #pragma message: EPOLLWAKEUP unsupported. Power management features may fail.
 #   pragma message "EPOLLWAKEUP unsupported. Power management features may fail."
