[Buildroot] gdbserver located outside *SYSROOT

[Buildroot] gdbserver located outside *SYSROOT

[Alexey Brodkin]

Hi Thomas,

I just realized that in pre-built ARC GNU tools gdbserver resides
outside of SYSROOT_DIR/ARCH_SYSROOT_DIR.

Historically we put gdbserver in top-level "target-bin" folder.

And I'm wondering how to deal with it to get proper copy of it onto
target if BR2_TOOLCHAIN_EXTERNAL_GDB_SERVER_COPY is selected.

 [1] Do we really need to re-consider placement of gdbserver for our
next release of GNU tools for ARC? Then what could be the best location?

 [2] Will setup of TOOLCHAIN_EXTERNAL_FIXUP_CMDS to cp gdbserver to some
related location be a good solution of the problem (if so then maybe
forget about [1] at least until we have multilibbed tools for ARC)?

Well, other toolchains usually put gdbserver in the sysroot or the
arch-sysroot, so it looks like a proper location to put it.

crosstool-NG toolchains put it in a specific directory, 'debug-root',
which stands side-by-side with the sysroot (not necessarily the best
move I did with that, but that's supported by Buildroot).

gdbserver, being a target executable, really has no place in the
top-level bin/ directory. It would be good to move it out of there.

Yes, using _FIXUP_CMDS is a good solution, and is made exactly for this
kind of situation. Just copy in into sysroot/bin/ and you're done.
