[Buildroot] [PATCH 1/2] arch/sparc: drop old SUN-specific variants

[Gustavo Zacarias]

Drop the old Sun-specific variants used in old workstations (pre-1997)
and other useless ones.

The V7 ISA is a very old cpu only used in the first Sun workstations,
the toolchain support is broken: the cpu doesn't do hardware div and
it's not handled elsewhere.

The sparclite is also a very old Fujitsu cpu only used in early 90s Sun
machines (includes f930 & f934).

The sparclet (tsc701) was a microcontroller-variant.

The supersparc and hypersparc are just V8 variants also used in old Sun
workstations/servers.

[Buildroot] [PATCH 2/2] qemu/sparc-ss10: switch to v8 optimization

[Gustavo Zacarias]

Switch to generic V8 optimization for gcc since we dropped the explicit
supersparc one and works just the same.

I don't know anything about sparc, but it sounds good - So committed,
thanks.
