Log Message:
midori: Append to CONFIGURE_ENV instead of redefining it (NFCI)

This is not a functional change in that case but the latter is more prone to
possible (accidental) error.

(Unrelated but interesting side-note: VALAC is exported via vala bl3 when
GNU_CONFIGURE is set... I think that it is better to not extend it though,
probably midori is just an exception that reuses it and we can just pass it
through CONFIGURE_ENV)
