Dear maintainers,
Compiling the suitesparse-graphblas failed for loong64 in the Debian
Package Auto-Building environment.
The error log is as follows,
```
......

/usr/bin/ld:

The full build log can be found at
https://buildd.debian.org/status/logs.php?pkg=suitesparse-graphblas&ver=7.4.0%2Bdfsg-1%2Bb1&arch=loong64.
Please consider the patch I attached (Add extra build cflags to fix
relocation R_LARCH_B26 overflow).
Based on attached patch, I have built suitesparse-graphblas_7.4.0+dfsg-1
successfully on locally.
