Unfortunately not. You could talk to Jussi Pakkanen, our meson
maintainer and upstream of meson, maybe he can help here.
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.
