It's asserting on this line:
assert(!CCGenDiagnostics && "stdin produces no crash reproducer");
I think during make buildenv the make framework will run cc --version
and ld --version to get at the compiler and linker version, but it could
be that it's doing some weird combination that hasn't been thought of.
