Libraries that overlap with the standard library must have explicit
extern declarations. Without something like pkg-config where the
libraries can publish this info, it's easiest to just hard-code the list
of troublesome libraries.
We control static/dynamic by only making one or the other available.
Apparently the default of prefer static causes duplicate symbols for the
standard library.
This provides more defaults that aren't required for compiling with
rustc, but standardize the output for inclusion in a distro.
Things like
- Where to install libraries
- Stripping rustc note sections
- Optimization by default
