Ok, Alpha can do it, just tested:
static int i;
int j __attribute__((visibility("hidden")));
int k[100] __attribute__((visibility("hidden"), section(".sdata")));
int foo (void)
{
  return i;
}
int bar (void)
{
  return j;
}
int baz (void)
{
  return k[0];
}

on CVS head, unfortunately it doesn't do this in visibility
backport for 3.2 (yet, I'll have a look at this next weak).
On SPARC, it is not possible until binutils/gcc/glibc are
changed for the proposed new relocs.
IA-64 is ok with both 3.2 backport and 3.3 mainline.

So it IMHO looks like we need configury test for this (which will be
unfortunately arch dependend, and have a default for not tested architecture
(use bootstrap map)).
