Zlib patch and gold arm-elf target bug report

[Doug Kwan (關振德)]

The test should not be removed as it runs fine with arm-*-*eabi for
Android and ARM Linux using EABI.  Configuring gold for arm-*-elf is
not really supported or tested.  Gold is by default not enabled unless
you configure with the --enable-gold option.
