[Qemu-devel] PATCH: qemu sparc host cleanup

[Ben Taylor]

This patch is a consolodation of patches and ideas from BlueSwirl, Martin
Bochnig and myself.

The patch is comprized of three parts:

1)  to more accurately set the compile flags on sparc hosts, with an eye
for sparc_v8plus and sparc_v8plusa, as well as sparc_v9, and leaving
the option for non-ultrasparc hosts to compile qemu.  Use of the 
ARCH_CFLAGS/ARCH_LDFLAGS at the top level guarantees that
specific host information is dissemnated throughout the build environment

If no default target is selected, sparc_v8plus is used for 32-bit, and sparc_v9
is used for 64-bit (sparc64)

2) cleanup of the Makefile.target for Sparc 32/64 and Linux/Solaris hosts,
reducing redundnancy of configuration parameters

3) enable sparc_v8plus and sparc_v8plusa to use the rtdc.  Prior to this
patch, sparc_v8plus and sparc_v8plusa targets were not able to use
the rtdc, and this makes the guests correctly pull the host clock.

This patch supercedes a previous patch I posted for Makefile.target cleanup.
