ld atm ends up calling the write() syscall on every char when displaying
an error message. For example:
$ echo 'main(){foo();}' | strace -f -ewrite gcc -x c -o /dev/null -
...
[pid 13035] write(2, ":", 1) = 1
[pid 13035] write(2, " ", 1) = 1
[pid 13035] write(2, "I", 1) = 1
[pid 13035] write(2, "n", 1) = 1
[pid 13035] write(2, " ", 1) = 1
[pid 13035] write(2, "f", 1) = 1
[pid 13035] write(2, "u", 1) = 1
[pid 13035] write(2, "n", 1) = 1
[pid 13035] write(2, "c", 1) = 1
[pid 13035] write(2, "t", 1) = 1
[pid 13035] write(2, "i", 1) = 1
[pid 13035] write(2, "o", 1) = 1
[pid 13035] write(2, "n", 1) = 1
[pid 13035] write(2, " ", 1) = 1
[pid 13035] write(2, "`", 1) = 1
...
That's just to write ": In function `main':". A slight optimization in
the vfinfo() func gives a much more reasonable syscall footprint:
...
write(2, ": In function `", 15) = 15
