What you are seeing is one of the "not so nice" features in ELF.
It is currently impossible to tell what OS a static ELF binary
is for, so the loader assumes (incorrectly) that it is a
native FreeBSD ELF binary and boom..
There is NO pretty fix for this except marking the files in
some way. We know the problem and the workaround, but infact
we need coorporation with Linux/SVR4/whatever to set a standard
for this, so its likely not to happen :(
