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]

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
