Install customer kernel and rebuild OFED failed

[heyinvidia]

After installed customer kernel, download MLNX_OFED_SRC-5.6-1.0.3.3.tgz and build followed the guide, run into failures

1. iser-5.6 rebuild failed
   Processing files: iser-5.6-OFED.5.6.1.0.1.1.kver.4.19.0_1.0.1.6.aarch64
   error: File not found by glob: /var/tmp/OFED_topdir/BUILDROOT/iser-5.6-OFED.5.6.1.0.1.1.aarch64/etc/depmod.d/zz02-iser-*.conf

2. need to add Note for CentOS: To build kernel RPM while running ARM container on x86_64 need to disable kernel's debuginfo package:
   cat > /root/.rpmmacros <<EOF
   %debug_package %{nil}
   %with_debuginfo 0
   %__debug_install_post %{nil}
   EOF
