When I just tried to emerge bind-tools on a newly installed system, it went through a bit of the configure process, and then it complained that it couldn't determine the object suffix or some similar sounding thing. FEATURES=-distcc makes it happier.
Steps to Reproduce:
reopen with output from emerge --info
I'm paying more attention to the similar bug,
By now, I'm thinking that the problem is some combination of autoconf and GCC
