Sorry I just realized that you may have implied that having a .globl in 
the object file ought to be sufficient to indicate that the symbol needs 
to be exported.  The glibc linker script however overrides this with 
{local: *} and if the linker doesn't honour that then ISTM that this 
ought to be a bug in the linker.  ld.bfd always gives preference to the 
linker script over symbol definitions in source and it seems like a 
simpler and more consistent rule.
