RE: [PATCH] Change gdbserver to use existing gnulib and libiberty

Hi Tom,

We're having trouble building cross toolchains after this change.

Before this we were able to build gdb running on HOST but build gdbserver running on TARGET.

After this change we can no longer do this since you can't link objects from different architectures.

Is this not a supported workflow anymore? Any suggestions how to do this after these changes?

Thanks,
Tamar
