From 9601f8274633eed6d015e12a4a5308dab4620763 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 9 Mar 2018 12:26:19 -0500 Subject: [PATCH] configure: Diagnose broken linkers directly Currently if the user's compiler works for creating .o files but their linker is broken such that compiling an executable from a C file does not work, we will report a misleading error message about the compiler not supporting __thread (since that happens to be the first test we run which requires a working linker). Explicitly check that compile_prog works as well as compile_object, so that people whose toolchain setup is broken get a more helpful error message.
