installed gdb doesn't work

[shruthb]

I get the following output when I run the gdb installed and none of the gdb commands succeed. Also tried searching for the directory that this outputs /usr/local/Cellar/riscv-gnu-toolchain/gnu/share/gdb/python but this really doesn't exist.

c4b301bae501:xv6-19au shruthb$ /usr/local/opt/riscv-gnu-toolchain/bin/riscv64-unknown-elf-gdb                                                                    
Python Exception <type 'exceptions.ImportError'> No module named gdb:

Limited Python support is available from the _gdb module.
Suggest passing --data-directory=/path/to/gdb/data-directory.

More work will be required to make riscv-gdb work with the host Python. We welcome any contributions to help with this.
