[PATCH v2 4/4] Gold/MIPS: Add MIPS64 support for --eanble-targets option

[YunQiang Su]

Currently, if we pass only mips64 triples to --eanble-targets,
gold itself will link fail:

/usr/bin/ld: /usr/bin/ld: mips.o: in function `gold::Output_reloc<9, true, 32, true>::sort_before(gold::Output_reloc<9, true, 32, true> const&) const':
./builddir-mips/gold/../../gold/output.h:1276:(.text+0x2b44): undefined reference to `gold::Output_reloc<9, true, 32, true>::compare(gold::Output_reloc<9, true, 32, true> const&) const'
/usr/bin/ld: mips.o: in function `gold::Output_reloc<9, true, 32, false>::sort_before(gold::Output_reloc<9, true, 32, false> const&) const':

/usr/bin/ld: mips.o: in function `gold::Output_reloc<9, true, 32, false>::sort_before(gold::Output_reloc<9, true, 32, false> const&) const':

Here, we add:
  mips64*el-*-* | mipsisa64*el-linux* for MIPS64 little endian;
  mips64*-*-* | mipsisa64*-linux* for MIPS64 big endian.
