sys-devel/autogen: override *_cv_* fro corss-case, bug #425174

A few autogen configure tests require running the program on machine:
    export ag_cv_run_strcspn=no
    export libopts_cv_with_libregex=yes

Pass these to get past ./configure. Autogen still reexecutes itself
at build time. Will need more fixes if feasible at all.
