How about something like:
ldverbose=$(ld --verbose)
first="$(echo "$ldverbose" | grep --line-number ^OUTPUT_FORMAT | cut -d: -f1)"
last="$(echo "$ldverbose" | grep --line-number ^OUTPUT_ARCH | cut -d: -f1)"
var_you_want="$(echo "$ldverbose" | sed -n "$first,$[$last-1]p")"

I don't speak perl, but all I do is calling programs in /bin, which I'm sure
is possible with it.

It might, and it might not.  If you use it, you are saying "elf32" may not be
in any other line.  This is clearly wrong, even if it works.
