Subject: [PATCH] add support for ARM hard-float ABI (fixes #5914)
This patch enhances Platform's ArchARM to include ARM ABI value. It also
tweaks configure machinery to detect hard-float ABI and to set it wherever
needed. Finally when hard-float ABI is in use, pass appropriate compiler
option to the LLVM's llc. Fixes #5914.
