Author: emaste Date: Fri Jan 2 15:36:29 2015 New Revision: 276539 URL: https://svnweb.freebsd.org/changeset/base/276539
Log: Update ELF headers to include additional defines The elftoolchain project includes these additional defines for various userland programs. Given that arch-specific defines are still interesting in the context of userland programs reading or writing ELF metadata, they should be included in top-level ELF headers. Remove duplicate defines from ARM and MIPS elf headers.
