```
As you can see, I want `llvm-bolt` to use instrumentation library: `$HOME/bin/bolt/lib~/bolt-lib/libbolt_rt_instr.a` but it searched for `/home/lib~/bolt-lib/$HOME/bin/bolt/lib~/bolt-lib/libbolt_rt_instr.a` and failed.

I think there must be something wrong when processing command line options?
