The verbose output is below. If I run the two commands on the command line,
they both succeed, but when I run them through build.py, the link command is
failing. I suspect that the process that gets created through python doesn't
inherit the environment with the PATH set, so it can't find the linker.

Interesting. Can you run the script in verbose mode so I can see the exact
commands it executes?
Not being able to find the linker is weird. Can you check whether you have
/usr/bin/ld on your system? Maybe we need to add something to the PATH? Is that
clang binary capable of producing executables when you run it manually?
