This isn't a new check, it has been there since 0.183.
If your libc doesn't provide obstack support you probably have to provide a
library that does to configure. What does config.log say precisely?

The previous version ported to FreeBSD was 0.179 and it didn't have such check
in configure.

Sources of obstack* functions are provided by the gnulib package but they
aren't built in that package - the sources are added to Makefile.am files here.

I had to remove the obstack configure check to make it pass.

---------------

Could you please make sure that elfutils builds on FreeBSD with clang?
Currently there are too many loose ends with elfutils.

We rely on people actually using FreeBSD and clang to make that happen. I don't
believe any of the active developers use such systems. But we are happy to take
patches if necessary.
