That is correct.  When you cross compile, the host and target are set differently.  For instance, I get

checking build system type... x86_64-unknown-linux-gnu
checking host system type... armv7hl-redhat-linux-gnu
checking target system type... armv7hl-redhat-linux-gnu

instead of

checking build system type... armv7hl-redhat-linux-gnu
checking host system type... armv7hl-redhat-linux-gnu
checking target system type... armv7hl-redhat-linux-gnu

I will not be able to run the ARM built executabled on the x86_64 machine. I have attempted to modify the makefiles to build the gen_tables executables for the x86_64 architecture but I realized that will cause the wrong header files to be brought in.  Even if I was able to get the correct header files brought in, they will not have the correct macros defined, possibly causing the wrong values to be brought into the header files.


Thanks,
