Description of problem:

ncbi-blast+ for some reasons do not use %configure macro. Part of this macro updates config.{guess,sub} files to the latest ones to get support for all new architectures (AArch64 in our case).

Version-Release number of selected component (if applicable):

2.2.28-1

How reproducible:

always

Steps to Reproduce:
1. fetch source rpm
2. rebuild for AArch64


Actual results:

~/rpmbuild/BUILD/ncbi-blast-2.2.28+-src/c++ ~/rpmbuild/BUILD/ncbi-blast-2.2.28+-src
