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).
