charset="utf-8" The -msoft-float switch is not available in older versions of Clang. Since we rely on the compiler to not generate floating point instructions unexpectedly, we block those old compilers now via a test in the configure script. Note that for some weird reasons, the Clang compiler only complains about the missing soft-float support if no other flags are passed via "-Wl,..." to the linker. So we have to use "compile_object" instead of "compile_prog" for this check.
