cross-gcc tgtarch=amd64 tgtabi=linux-gnu, no party

[Kjell Tore Ullavik]

I'm trying to build devel/cross-gcc like this

# make TGTARCH=amd64 TGTABI=linux-gnu

only to have my dreams and aspirations crushed like this

Stop in /usr/ports/devel/cross-gcc.

Am I missing something?
Interestingly I find no open bug reports whatsoever on cross-gcc
