Subject: When an archive fails to build, print the path

Currently the output on failure is as follows:

       Compiling block-buffer v0.10.4
       Compiling crypto-common v0.1.6
       Compiling digest v0.10.7
       Compiling sha2 v0.10.8
       Compiling xz2 v0.1.7
    error: failed to build archive: No such file or directory

    error: could not compile `bootstrap` (lib) due to 1 previous error

Print which file is being constructed to give some hint about what is
going on.
