Automate doom, quake, and scimark2 builds

Mention RV32F explicitly.

[vacantron]

The current prebuilt binaries are built with -march=rv32im option. I'd like to keep quake been built without F extension for the consistency.

SciMark2 should be built in RV32F since it reports a composite score in approximate Mflops (Millions of floating point operations per second).

Got it. Should we also build quake with rv32f? I feel the execution is smooth when building with rv32im.

Quake needs to be compiled with RV32IMF. Otherwise, it is unlikely to function properly.

[vacantron]

I found quake is already built with RV32IMF within its Makefile. I'll update the document later.

I think this error was caused by the script from https://apt.llvm.org/llvm.sh. In line 160: wget -qO- https://apt.llvm.org/llvm-snapshot.gpg.key | tee /etc/apt/trusted.gpg.d/apt.llvm.org.asc. It seems to fail to retrieve the GPG key (maybe the Internet issue?).
