[PATCH 52/59] fixup! libctf, link: tie in the deduplicating linker

[Nick Alcock]

We can't use -1 here without causing trouble on platforms with 32-bit
ssize_t.  We also have to cast the input to labs to long int to allow
for platforms on which ssize_t is long long (it's easier to do that
than it is to use llabs, which is less common: counts of inputs that
exceed 32 bits are prohibited anyway so we don't care about any
precision loss that high up.)

So much work for such an unlikely error case :)
