For some reason, `gold` will produce a bad executable on linux when
building against the static `depends`. The build runs fine, is
deterministic, but running `bitcoind` or `bitcoin-qt` make them stuck -
they won't return, no error, won't shutdown and need to be killed.
The last debug.log line is:
```
Using at most 125 automatic connections (1024 file descriptors available
```
This needs to be investigated, but for now the gold linker is disabled.
