From 6e6ecacebf521b5ce91d8c141ca095e180fe762f Mon Sep 17 00:00:00 2001 From: Michael Brown Date: Tue, 5 Apr 2011 14:59:27 +0100 Subject: [build] Refuse to attempt building with the GNU gold linker GNU gold (part of newer binutils builds) does not appear to be designed to support generic linker functionality, since its source code contains several Linux-specific hard-coded assumptions about the layout of ELF binaries. Attempting to build iPXE using GNU gold will generally cause some kind of "linker internal error". Provide an explicit error message suggesting the use of GNU ld instead.
