# get the crt<X>.o built. However, we need to call it again after

|
# gcc-intermediate has been built, otherwise the configure script
|
|
# doesn't realize that libgcc has been built, and doesn't link the C

# library properly with libgcc, which causes build failure down the

# road. We will have the opportunity to simplify this once we switch
