How can this even work?

The value of GIR_EXTRA_LIBS_PATH will be that of the last package
parsed, and this is robably not what you really intended.

If a package needs to pass extra environment variables, there is already
this (at least for most of our package infras, I believe):

    FOO_CONF_ENV
    FOO_MAKE_ENV

... which packages can set to add environment variables.
