Closed issue by bobertlo on void-packages repository

https://github.com/void-linux/void-packages/issues/34387

Description:
I am trying to do a revbump on libgit2 and julia is the only build not working. I checked out master and it is not able to rebuild from source.

Error:
```
getarch_2nd.c:14:35: error: 'SGEMM_DEFAULT_UNROLL_M' undeclared (first use in this function); did you mean 'SHGEMM_DEFAULT_UNROLL_M'?
   14 |     printf("SGEMM_UNROLL_M=%d\n", SGEMM_DEFAULT_UNROLL_M);
      |                                   ^~~~~~~~~~~~~~~~~~~~~~
      |                                   SHGEMM_DEFAULT_UNROLL_M
```

It looks like this error: https://github.com/xianyi/OpenBLAS/issues/2769

I will try to look into this further when I have time. I am also wondering if this should be specified anyway are we generating code specific to the host/builder CPU microarchitecture?
