work around regression building for armhf with clang (compiler bug)
commit e4355bd6bec89688e8c739cd7b4c76e675643dca moved the math asm from external source files to inline asm, but unfortunately, all current releases of clang use the wrong inline asm constraint codes for float and double ("w" and "P" instead of "t" and "w", respectively). this patch adds detection for the bug in configure, and, for now, just disables the affected asm on broken clang versions.
