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: https://en.wikipedia.org/wiki/Xeon#Nocona_and_Irwindale Jaguar is from the Bobcat family, so use the BOBCAT openblas target: https://en.wikipedia.org/wiki/List_of_AMD_microprocessors#Bobcat_core_architecture_(APU) [Peter: add Jaguar as pointed out by Arnout] Signed-off-by: Peter Korsgaard <peter@korsgaard.com> (cherry picked from commit 5e6fa93483caac317ab8844feb2ae9c07078a6c8) Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
