I will try my fix (leaving the t-linux name alone for now). I'm an idiot: I've just copied the relevant lines from gcc/config/t-linux, forgetting that libgcc-glibc.ver still lives in gcc/config. ibgcc/config/t-linux should be # Override t-slibgcc-elf-ver to export some libgcc symbols with # the symbol versions that glibc used. SHLIB_MAPFILES += $(gcc_srcdir)/config/libgcc-glibc.ver instead. AFAICS, you will need both the generic gcc/config/libgcc-glibc.ver and gcc/config/ia64/libgcc-glibc.ver.
