[LEDE-DEV] [PATCH] gdb: bump to 8.0.1

[Stijn Tintel]

Since version 8.0, there is a dependency on libstdc++, and gdb does not
build against uClibc++. Disable building of the libstdc++-v3, instead of
adding a hard dependency on libstdcpp. Adding a ~350KB dependency to
gdbserver will make it hard for people to use it on 4MB flash devices.

Fixes CVE-2017-9778.
