[Buildroot] [PATCH] package/binutils: handle gprofng as an optional feature

binutils 2.39 added support for gprofng, a new profiler (see
https://www.phoronix.com/news/GNU-Profiler-gprofng).
This new profiler is enabled by default, but it requires bison on the
host.
In order to handle this, this commit:
- Adds a new option BR2_BINUTILS_GPROFNG, which allows to
enable/disable gprofng in host-binutils
- Unconditionnally disables gprofng for the target binutils, based on
the idea that in a Buildroot context the analysis of profiling data
is generally done on the host system. This can of course always be
revisited later by adding a new option to the target binutils
package.
