I haven't had this exact error before, but we have seen similar in the
past. What's probably relevant is the version of your compiler
(gcc --version). The last time we saw this the workaround deployed was

Trying similar for OSeekableInputStreamWrapper might help.

As an aside, I don't think the linker error is due to the configure
flags used here, but --with-distro=LibreOfficeOnline is an unusual
config choice to pick (and it already includes --without-system-libxml)
and will result in a libreoffice build that doesn't have a gui so if it
does build launching it won't give you something you can interact with.
