build spike-sys v0.1.1 error

[Taolaw]

While compiling spike-sys, I encountered the following error. It seems to be missing a specific static library, but I couldn't find more information about this error. I found this link related to the library, and the triggering condition is simply:

ckb-vm-test-suite/spike-sys$ cargo build
   Compiling spike-sys v0.1.1 (/home/ckb-vm-test-suite/spike-sys)
error: could not find native static library `spike-interfaces`, perhaps an -L flag is missing?

error: could not compile `spike-sys` (lib) due to previous error

Have you installed clang? The error says the problem is with building spike-interface, I suggest you execute build.sh manually first so you can get some meaningful output.
