glibc & eglibc: fix mips DT_MIPS_RLD_MAP checking
On mips target, binutils currently sets DT_MIPS_RLD_MAP to 0 in dynamic section if a --version-script sets _RLD_MAP to local. This is apparently a binutils bug, but libc shouldn't segfault in this case. Add sanity check on the entry to avoid segfault, fixes [BUGID #287]. Signed-off-by: Qing He <qing.he@intel.com>
