After discussing at the Buildroot meeting, we decided to reject this
patch. Indeed, we believe this additional wrapper is not really needed,
and hides some more magic which we prefer to keep visible to the user.

What we could do is to make it a bit easier for users to find the
gdbinit file by having a "staging" symlink pointing to the sysroot,
installed in the host directory. This way, even if your toolchain is
installed in /opt/br-baz/, you can do:

/opt/br-baz/usr/bin/<blah>-gdb -x /opt/br-baz/usr/staging/usr/share/buildroot/gdbinit

Best regards,

Thomas
