Bug#896012: Regression from gcc-7 7.3.0-16

[<Mario.Limonciello@dell.com>]

Package: gcc-7
Version: 7.3.0-16

The fwupd project as one of the CI tasks runs packaged builds and lintian after the build.
CI recently started failing with this error:

E: fwupd: library-not-linked-against-libc usr/lib/x86_64-linux-gnu/fwupd-plugins-3/libfu_plugin_upower.so
E: fwupd-tests: library-not-linked-against-libc usr/lib/x86_64-linux-gnu/fwupd-plugins-3/libfu_plugin_test.so

We narrowed it down to be caused after upgrading to GCC 7.3.0-16 from Debian testing.
Builds with 7.3.0-15 and no source changes to fwupd are not affected.

We also found that changing compiler optimization (-O2 to -O0) with the new GCC this error
goes away.
