    Use the gold linker for linux/ARM and android/ARM targets. · 71fcc4c0
    Erik de Castro Lopo authored
    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
    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).
