cover ARM hf support

This patchset adds the newly added hard float convention for naming the dynamic linker. We have a tune feature to denote hf calling convention already therefore this patch uses that feature to decide on configuring the toolchain to be soft float or hard-float call conventions by default.

The following changes since commit e6333825c3482a559a0c0499e17f8f48d3042ddf:

tune-mips64.inc: Add new tune file for mips64 big-endian (2012-05-20 20:24:37 -0700)

+ARM: Define HAVE_ARM_PCS_VFP in config.h.
+
+If the compiler and flags would select the hard-float ABI
+then the ARM configure fragment will set HAVE_ARM_PCS_VFP.
+This is later used by the ARM shlib-versions to select
+the appropriately named dynamic linker.
