[Buildroot] Segmentation fault while trying to remote debug with GDB and GDBServer

[Oded Hanson]

What about the include path when compiling from eclipse ? Any chance its using my host include files ?

I can see that its using the cross compiler for sure,  but don't see where the include path is set.

The Eclipse plugin does set the solib-path (see
https://github.com/mbats/eclipse-buildroot-toolchain-plugin/blob/master/org.buildroot.cdt.toolchain/src/org/buildroot/cdt/toolchain/BuildrootLaunchConfigurationTabGroup.java#L70),
but that is apparently insufficient for gdb to find the correct dynamic
linker, especially when the host and target architectures are identical.

Since there is apparently no way in Eclipse to set a gdb sysroot, I
believe the only solution is for the Eclipse plugin to generate a
simple gdbinit file:

set sysroot /path/to/staging/directory

and then instruct Eclipse to use it.
