Improve Makefile

- support different config styles

The config style can be either 'auto' (default) or 'pkgconfig'.

Note:

The 'auto' config style will only work properly when building
on the same host the binary is supposed to run on.

- use more commonly used variable names
- use `install` instead of `cp` when installing
- add uninstall target
