The -mcall-ms2sysv-xlogues option is supposed to work on Solaris and
Darwin, but my changes to config.host weren't adding the sav/res stubs
to libgcc and the assembly code wasn't compatible with their assemblers
either.

* Change config.host to build -mcall-ms2sysv-xlogues sav/res stubs on
  Solaris and Darwin.
* Replace .macro/.endm with cpp macros
* Replace .global with .globl
* Append __USER_LABEL_PREFIX__ when defined (via ASMNAME macro).
* Only use .size when __ELF__ is defined.
* Only use .hidden when both __ELF__ and HAVE_GAS_HIDDEN are defined.
