--- Comment #3 from Alex Richardson <arichardson@FreeBSD.org> ---
That suggests to me that all of the bootstrap tools are not executable since
they are missing the notes section. You should see it with all other tools
built during bootstrap but since base 8e1c989abbd1db4dac5b2149886012d43e27b9a9,
tblgen will probably be the first since the host tools can be used for
everthing else If you build with BOOTSTRAP_ALL_TOOLS=1 it should fall over
earlier.

What does `readelf --notes
/usr/obj/usr/src/riscv.riscv64/tmp/obj-tools/usr.bin/clang/clang-tblgen/clang-tblgen`
print?
