you have to create the language in Polylang with ‘am’ for both language code and locale. As soon as you will publish some content in that language, it will show up in the language switcher. if you want to use a flags, then create a directory wp-content/polylang and put the flag am.png or am.jpg in in that directory. the flag won’t show up on admin.
After that, you will probably need to translate at least part of your theme. If it is internationalized, you should have a .pot file somewhere in your theme directory. Copy this file to am.po and translate the strings using poedit. If your theme has no .pot file, please refer to http://wordpress.org/support/topic/plugin-polylang-how-to-internationalize-a-theme
As far as I know, WordPress is not available in Amharic yet, but you may need to translate some parts of WordPress (for example months if your site diplay monthly archives). In that case you will need to get the WordPress .pot files from http://svn.automattic.com/wordpress-i18n/pot/tags/3.5.1/. If you don’t need to translate your admin, all the strings you will have to translate should be found in wordpress.pot that you will have to copy to wp-content/languages and rename to am.po
