openblas: drop SSE_GENERIC target
Fixes #10856
The SSE_GENERIC target fails to build with a "sgemm_kernel.o: No such file
or directory" error. Several upstream bug reports exist for this:
https://github.com/xianyi/OpenBLAS/issues/502
https://github.com/xianyi/OpenBLAS/issues/685
In both cases, upstream suggests using a different target definition
instead. E.G. from issue 685:
You may use NORTHWOOD on x86: make TARGET=NORTHWOOD that uses SSE2
instructions. It's very hard to find non-SSE2 x86 CPUs today. For x86-64
use the PRESCOTT target
So drop the SSE_GENERIC target. The only x86_64 variant we support not
covered by a more specific openblas target is the default variant, nocona
and jaguar.
Nocona was a Xeon variant of the P4 "Prescott" architecture, so use the
PRESCOTT openblas target:

Jaguar is from the Bobcat family, so use the BOBCAT openblas target:

[Peter: add Jaguar as pointed out by Arnout]
