Browse Source 
Buildroot commit b08ac7636d bumped the
package to version 0.3.31 and introduced a build error

linktest.c:(.text.startup+0x6f4):
 undefined reference to `openblas_set_threads_callback_function'

which according to https://github.com/OpenMathLib/OpenBLAS/issues/5607
was introduced by upstream commit
879497990f
that was first included in version 0.3.31.

This patch adds another upstream commit to fix the problem.
