It did build on the buildbot.

​http://packages.macports.org/gcc10/gcc10-10.3.0_0.darwin_11.x86_64.tbz2

I ran into this on one of my 10.7 machines while building gcc-10.2 as well. It then did build from a clean slate by deactivating all ports first.

gcc is a bit delicate; on MacPorts we have a bit of a problem specifying the assembler, which somewhat is random for complicated reasons...I think that might be relevant to this.

Fixed with latest versions.
