utils: Change `substitute*' to allow iteration over several matches.
* guix/build/utils.scm (substitute): Do not pass the OUT to PROC; use `list-matches' instead of `regexp-exec' and pass a list of matches to PROC. Expect PROC to return a string, and output that. Fold over RX+PROC in order. Use `(read-line p 'concat)' to include the trailing delimiter in LINE. (substitute*): Produce code to iterate over the matches, and return a string, which includes anything from the original line that's in between matches. * distro/base.scm (gcc-4.7, glibc): Adjust accordingly: remove use of (ice-9 regex) and `regexp-substitute/global'; return a string.
