loongarch64 sdot:dsdot_n_1 test fails

[fawltylanguage]

On a QEMU loongarch64 VM with GCC 15.2.1 and

 make BINARY=64 USE_THREAD=1 NO_LAPACK=1 NO_LAPACKE=1 NO_AFFINITY=1 NUM_THREADS=64 -j6

I get

TEST 27/124 dsdot:dsdot_n_1 [FAIL]     
  ERR: test_dsdot.c:47  expected -2.393e-03, got 2.248e+00 (diff -2.250e+00, tol 1.000e-13)
