Umm the canonical host name must be something like
bfin-unknown-linux.

Okay, thanks for the hint.

The strange thing is that libtool checks if global_symbol_pipe
needs to handle underscore with a general check, not with
a host name check.

But this knowledge is not used for archive_expsym_cmds.
For blackfin the only difference is undescore, otherwise it
looks like regular linux. So special casing bfin-linux looks
excessive. But if this okay with libtool maintainers, I may
try to create a patch that does exactly that.
