Subject: [PATCH] build: Add no-exceptions sanity check

Some distributions pass -fexceptions in a way that overrides vte's

own -fno-exceptions. This is a hard error; fail the build.

See https://gitlab.gnome.org/GNOME/gnome-build-meta/issues/207

(cherry picked from commit ff72577bd7d84c30faca3285d7ed4e7f75194f98)
