The r_ldsomap field is specific to Solaris (part of librtld_db), and should never be accessed for Linux. glibc is planning to add a field to support multiple namespaces. But there will be no r_ldsomap when r_version is bumped to 2. Add linux_[ilp32|lp64]_fetch_link_map_offsets to set r_ldsomap_offset to -1 and use them for Linux targets.
