Would be nice for a build/config person to weigh in or to upgrade and make bullet proof the system against such failures. My take, by default, the compile line should do something useful, and that should be enough for autoconf style tests to smell the library. Now, we can observe that Steve's mips-mti-elf newlib port apparently violates that, but it is lost on me why that is and why that is a good thing. Steve? Is there some reason why by default, a suitable linker script can't be added by the compiler, or, if none suitable, a stub one that isn't suitable in general, but, is complete enough to allow autoconf to function normally?
