From 0ef74c7496fd3c526b2259f86326eca4b3a03b78 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Tue, 24 Nov 2015 14:55:46 +0000 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.
