Looking further into this error, errno 84 is EILSEQ, "illegal byte
sequence". The error is raised during the 'patch-source-shebangs' phase,
while patching  ./gcc/testsuite/gdc.test/compilable/test13512.d  This
file has the shebang

        #!/opt/dmd/ÐÒÏÂÙ/rdmd

This in turn seems to be tripping up this line in guix/build/utils.scm:1094 :

                 (and=> (and line (regexp-exec shebang-rx line))

I'm not sure why I don't hit this error when building gcc-toolchain.
Perhaps there is different locale information in the build environment
without glibc.
