elfutils-0.185-static-inline.patch

It's not readily reproducible on my system (probably due to slight difference of compiler flags). Can you try the following patch to see if it works?

Also, can you expand -march=native using https://wiki.gentoo.org/wiki/Gcc-ICE-reporting-guide#Expand_-march.3Dnative.2C_exact_gcc_version_and_other_system-specific_options
