Sounds good, although we need to pick up __executable_start too I
think; from my ld --verbose:
# PROVIDE (__executable_start = 0x400000); . = 0x400000 + SIZEOF_HEADERS;
How about this?
$ld --verbose | sed \
-e '1,/==================================================/d' \
-e '/==================================================/,$d' \
-e "s/[.] = .* [+] SIZEOF_HEADERS/. = $textseg_addr + SIZEOF_HEADERS/" \

Both sound reasonable, although I don't have an easy way to test
either platform at the moment. We can always make those changes
after, or I am happy to respin the patch.
