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.
compiling main.c -> exec-next-instruction.test.tmp-main.o

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?
