<pre>Clang on Fedora ARM does not work well because clang does not
recognize the Fedora ARM triplets and fallback to software floating point,
causing build failures like this:
clang: warning: unknown platform, assuming -mfloat-abi=soft

Earlier I tried a simple naive patch like:
--- llvm-3.2.src/tools/clang/lib/Driver/ToolChains.cpp~ 2012-12-17
00:59:27.000000000 +0900
+++ llvm-3.2.src/tools/clang/lib/Driver/ToolChains.cpp 2013-02-12
19:18:00.755164292 +0900
@@ -1054,10 +1054,12 @@
static const char *const ARMLibDirs[] = { "/lib" };

static const char *const ARMHFTriples[] = {

but it was not sufficient - maybe fixes are also needed to on the llvm side,
perhaps?
(Similarly ppc64-redhat-linux is also not supported.)</pre>
