Fixed bug if mpg123 is statically linked

1. Issues warning if no modules (aka no ltdl), which is probably not
   what you want.
2. Bug would mess up permissions if no modules were found.
Fixed compiling multiple libraries at once

1. Wasn't processing the $LIBRARY variable correctly.
Partial renaming of library to component

1. Library isn't 100% accurate, with Love2d and chrpath.
