Missing dependencies on Linux

[nelimee]

Describe the bug sw needs flex and bison to work and it seems to be missing from the README.

Expected behavior Dependencies are written on the README or on the documentation.

To Reproduce Steps to reproduce the behavior:

1. Get a fresh Linux (Fedora 31 in my case).
2. Download sw binaries and run sw build -static as written in the README.
3. An error message for flex is thrown. Once flex is installed, a similar error is thrown for bison.

Performing 63 check(s): pub.egorpugin.llvm_project.llvm.support_lite-master (support_lite), config 183752
Exception in file D:/dev/cppan2/client2/src/sw/builder/command.cpp:344, function prepare: passed program 'flex' is not resolved (missing): generate: "/home/*****/.sw/storage/pkg/d2/69/81cc/obj/bld/837326/bdp/fb/range.ll/range.ll.cpp", 4236949366111544608, # of arguments 5

Information:

• Happened to me the 11/04/2020 with a fresh version of sw. I updated sw since then...
• Fedora 31

Hi,

True. Non-windows systems need flex and bison because I did not package them for those OS yet. I'll try to fix it.
