Thank you! Reinstalling libtool-base helped on every buildhost where I
had this problem. Does adding/removing

   PKGSRC_COMPILER=        ccache gcc

in mk.conf count as "changing the compiler behind libtools back"?
Or adding/removing

   USE_CWRAPPERS=yes

?

These were the only parameters I played with recently.
