When an external toolchain is used, and the user has chosen to copy the external toolchain gdbserver to the target, then we should allow the user to build a gdbserver and/or a cross-gdb: the ones of the external toolchain should be used. The reasoning is that one must use a gdbserver and cross-gdb of identical versions to be sure that debugging will work properly. Change suggested by Yann E. Morin.

GDB, the GNU Project debugger, allows you to see what is
|
|
going on `inside' another program while it executes -- or
|
|
what another program was doing at the moment it crashed.
|
|
|
|
This option allows to build gdbserver and/or the gdb
|
|
debugger for the target.
|
|
|
|
For embedded development, the most common solution is to
|
|
build only 'gdbserver' for the target, and use a cross-gdb
|
|
on the host. See BR2_PACKAGE_HOST_GDB in the Toolchain menu
|
|
to enable one. Notice that external toolchains often provide
|
|
their own pre-built cross-gdb and gdbserver binaries.
