glibc & eglibc: fix mips DT_MIPS_RLD_MAP checking

Browse Source 
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].
