Well, I see "-Wl,--version-script=libgcc.map" on the link line now but I
still get an error during the link:
/wsp/sje/gcc_git/gcc-ia64-debian-linux-gnu-gcc/ia64-debian-linux-gnu/bin/ld: ./libgcc_s.so.1.tmp: version node not found for symbol _Unwind_GetBSP@GCC_3.3.2

I think the contents of the map file may be wrong. This error involves a different symbol then when the
mapfile was missing.
From the log file:
sed -e 's/__PFX__/__/g' < /wsp/sje/gcc_git/src/gcc/libgcc/libgcc-std.ver.in > libgcc-std.ver
cat libgcc-std.ver /wsp/sje/gcc_git/src/gcc/libgcc/../gcc/config/libgcc-glibc.ver | ...
I am not sure I am getting the right libgcc-*.ver files yet. I think I need gcc/config/ia64/libgcc-glibc.ver
and/or gcc/config/ia64/libgcc-ia64.ver and I am not sure I am getting them.
I do see:
echo SHLIB_MAPFILES = 'libgcc-std.ver $(gcc_srcdir)/config/libgcc-glibc.ver $(gcc_srcdir)/config/ia64/libgcc-ia64.ver $(gcc_srcdir)/config/ia64/libgcc-glibc.ver' >> tmp-libgcc.mvars
So maybe I am getting the right files, I'm just not sure.
