The Linux ld (has has been noted already) is the same as the freebsd
one. It also requires that you have a *.so filename present. The
reason is that ELF does not enforce any semantics on the SONAME of a
library, so it's perfectly legitimate to have a libfoo.so.5-pizza-6.
Now, if you have libfoo.so.5-pizza-6 and libfoo.so.5-sushi-3, how is
ld supposed to guess which one is the "greatest" value?
