Bug#909846: libglib2.0-dev: absolute paths in gio-2.0.pc break reverse dependencies

[Adrian Bunk]

Package: libglib2.0-dev
Version: 2.58.1-1
Severity: serious
Control: affects -1 src:tpm2-abrmd src:playerctl

https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/tpm2-abrmd.html

...
checking for GOBJECT... yes
checking for SAPI... yes
checking for /usr/bin/gdbus-codegen... no
configure: error: *** gdbus-codegen is required to build tpm2-abrmd


https://gitlab.gnome.org/GNOME/glib/issues/1521 even mentions
that this is known to break at least one reverse dependency.

How on earth could it happen that this was anyhow backported
to a stable branch?
