I've never gotten this error on a cross-compile build, but I have gotten it on an rfnoc build. In my case, the linker was finding headers from a system install of gnuradio and trying to use those instead of the fresh ones generated by make. I might uninstall any repository installs of gnuradio or temporarily muck with some environment variables so make only finds your local, up-to-date header files.
