This port's Makefile sets:

ld is designed to produce output in a single architecture only, so that doesn't
work for universal builds. But when the compiler calls ld, it does so once for
each architecture, then "lipo"s the results together.
I thought I would be clever and just replace "ld" with ${configure.cc} and that
would work, and it did on Yosemite beta. On every previous system however it
caused clang to experience an assertion failure, so I must not be doing this
right.
What is the right way to invoke clang or gcc as if it were ld so that it does
the multiple-ld-and-lipo dance for me?
