Most of the problem is in systemd's top meson.build file:

# the oss-fuzz fuzzers are not built with -fPIE, so don't
# enable it when we are linking against them
if not fuzzer_build
         possible_cc_flags += '-fPIE'
         possible_link_flags += '-pie'
endif

This is a highly questionable method of enabling PIE support in the 
presence of files
where -fPIC may be used.  It also adds -pie to link commands with -shared.

Since 0.49.0, meson has a b_pie option.  Another option that is relevant 
here is b_staticpic.
I don't know if they can work together.

It looks like the merging fix in gcc will be backported to gcc-8.

As a work around, you could disable LTO on hppa by setting 'b_lto=false' 
in debian/rules.
