Delete chipyard/.classpath_cache and retry.

Oh I'm dumb...

For FPGA it should be SUB_PROJECT=[arty|arty100t]

so

make SUB_PROJECT=arty bitstream

Then it raises the following error

> make SUB_PROJECT=arty100t bitstream

And deleting the .classpath_cache directory solves the error:

rm -rf ./chipyard/.classpath_cache
