Author: marcel Date: Thu May 24 20:12:46 2012 New Revision: 235929 URL: http://svn.freebsd.org/changeset/base/235929 Log: Allow building for the PowerPC EABI by providing a dummy __eabi() function. The purpose of the __eabi() function is to set up the runtime and is called first thing by main(). The runtime is already set up for us prior to caling main, so there's nothing to do for us in the EABI case.
