I have an early draft to explain the libraries here:
https://bitbucket.org/timosi/minlibd/wiki/libc_vs_libgcc
It is the Linux point of view but the basics are the same.

It would be hard to write generic patterns that describe all 
possible language features for all possible target systems. It is 
easier to put them into a separate library that is common for all 
apps. Some simple things are math with mixed types and fp math, 
more complex things are for example thread and exception handling.
