RE: serial vs parallel for ar

[Cesar Crusius]

This is wrong. There's no target for the library at all, which goes somewhat 
against the point of using make. In other words, if you want to 'make a 
library,' you want to tell make 'how to make a library.' But you aren't.

What you want is

<libname>: <objects>
        <create/update libraries>

<object>: <source>
        <compile object>
