[Buildroot] [PATCH v2 2/5] package/gdb: bump to version 8.1

[Yann E. MORIN <yann.morin.1998@free.fr>]

Thomas, All,

On 2018-02-05 22:10 +0100, Thomas Petazzoni spake thusly:
> From: Romain Naour <romain.naour@gmail.com>

> 
> gdb 8.1 has a new optional dependency on mpfr, which according to the
> NEWS file:
> 
>    GDB now uses the GNU MPFR library, if available, to emulate target
>    floating-point arithmetic during expression evaluation when the
>    target uses different floating-point formats than the host.  At
>    least version 3.1 of GNU MPFR is required.
> 
> So for the target gdb, this is unnecessary, and therefore we
> forcefully disable mpfr support by passing --without-mpfr.
> 
> For the host gdb, it would potentially be useful, but since it's a new
> feature that isn't essential, we for now keep it disabled as well. An
> option may be added later if needed.

Agreed.

And there you would have added:

    select BR2_PACKAGE_GDB_NEEDS_CXX11

Otherwise;
