Hi maintainers,
Compiling the openblas failed for loong64 in the Debian Package
Auto-Building environment.
The build error log is as follows,
```
......
/usr/bin/ld: ../libopenblasp-r0.3.28.so: undefined reference to
'blas_set_parameter'
collect2: error: ld returned 1 exit status
make[4]: *** [Makefile:208: ../libopenblasp-r0.3.28.so] Error 1
make[4]: Leaving directory '/<<PKGBUILDDIR>>/0-openmp/exports'
make[3]: *** [Makefile:144: shared] Error 2
......
```
The full log can be found at
https://buildd.debian.org/status/logs.php?pkg=openblas&ver=0.3.28%2Bds-2&arch=loong64.
The above question(undefined reference to 'blas_set_parameter') has been
fixed in upstream.
Please check https://github.com/OpenMathLib/OpenBLAS/pull/4877.
You can also consider the patch attached(pull from upstream).
I have built openblas 0.3.28+ds-2 successfully in my local ENV and all
test cases passed.
