The removal of the wheel caching code
(Ia140dc34638d893b92f66d1ba20efd9522c5923b) removed the install of the
"devlib" packages, which was being done with a call in
tools/build_wheels.sh
The idea of "devlibs" and "general" seems to be pretty much the same
thing -- global build requirements. I have removed the unused devlibs
files, and moved any missing packages into the "general" package
install file.
