 Use the gold linker for linux/ARM and android/ARM targets.

 Fixes #8976 and #9873 by making use of the Binutils ld.gold
 linker explicit whenever the target is linux/ARM or android/ARM.
 This does not affect iOS where Apple provides its own linker.

 In order to achieve this, we need to add `-fuse-ld=gold` to
 the SettingsCCompilerLinkFlags setting and set
 SettingsLdCommand to `ld.gold` (or `${target}-ld.gold` when
 cross-compiling). In addition, simplifying the use of
 `$(CONF_GCC_LINKER_OPTS_STAGEn)`.

 This patch was tested by ensuring that the following worked
 as expected:

   * Native builds on linux/x86_64 (nothing changed).
   * Native builds on linux/arm (and uses the gold linker).
   * Linux to linux/arm cross compiles (and uses the cross
     gold linker).
