Hi,

SH4 of atlas library has problem that unresolvable reference to symbol
__sdivsi3_i4i.

   las-base/atlas/:
dpkg-shlibdeps: warning:
debian/libatlas3gf-base/usr/lib/atlas-base/libatlas.so.3gf.0 contains
an unresolvable reference to symbol __sdivsi3_i4i: it's probably a
plugin.
dpkg-shlibdeps: warning: 1 similar warning has been skipped (use -v to see it).

This is because libgcc_s.a has __sdivsi3_i4i. This is a specific
problem on Renesas SH.
Therefore, it is revised if libatlas.so.3gf.0 links libgcc_s as follows.

  ld  -shared -soname libatlas.so.3gf -o libatlas.so.3gf.0
--whole-archive libatlas.a --no-whole-archive -lc -lpthread -lm
-L/usr/lib/gcc/sh4-linux-gnu/4.4.5/ -lgcc_s

I made the brief patch which revised this problem.
Could you check this patch?

Best regards,
  Nobuhiro
