When a library path contained the library name it was eagerly matched
libfwupd.so.2 => /build/fwupd-1.0.5/build/libfwupd/libfwupd.so.2 (0x00007ffff7bbd000)
^^^^^^^^^^^^^^^^^^^^^^
libgweather-3.so.15 => /build/libgweather-3.28.0/build/libgweather/libgweather-3.so.15 (0x00007ffff7bae000)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
which lead to a broken shared library path in the generated GIR file.
This patch allows the soname on the left-hand side of the arrow to
be matched to avoid the trap of the right-hand side. A negative
lookahead had to be added to select the store path, since only
the first match is taken into account.
libglib-2.0.so.0 => /nix/store/dqlc8y4phlg1hmdbwkhqfwhnxcac88d1-glib-2.56.0/lib/libglib-2.0.so.0 (0x00007ffff6400000)
This will not fix non-GNU platforms, where the soname is not printed
first, but we cannot do much without structured ldd output.
