I think this is just a matter of strip encountering files that aren't of
the architecture of the current system. qemu is a good example of where
this fails:

/usr/bin/strip: Unable to recognise the format of the input file

and file reports this as...

pkg/usr/share/qemu/openbios-sparc32: ELF 32-bit MSB executable, SPARC,
version 1 (SYSV), statically linked, stripped

These are files that are shipped precompiled and prestripped.
