060741e77d Use $(my_prefix)OS instead of HOST_CROSS_OS 
The latter is not module-specific and affects all host modules.  Also
remove the check for LOCAL_IS_HOST_MODULE and use  $(my_prefix)OS.

This should be future-proof, where may use different configurations of
cross-compilations across Linux, Darwin, Windows.

Test: m native

4ad173788e Third try to enable clang lld as default linker. 
Note of existing configurations:
  * When lld is used, llvm-strip and llvm-objcopy are also used.
  * darwin host modules do not use lld.
  * lld can be disabled locally with use_clang_lld:false in Android.bp
    or LOCAL_USE_CLANG_LLD:=false in Android.mk.

Test: make checkbuild, boot and run bionic and system/core native tests

da8febf39c Revert "Revert "Set global default to use lld."" 
This reverts commit 44988be862.

Three known build failures with lld are fixed by
(1) adding --no-fatal-warnings to link
(2) disable LLD for some PGO build targets
(3) disable LLD for some art oatdump tests, pending c/681542

32427d6903 Add USE_CLANG_LLD and LOCAL_USE_CLANG_LLD 
* Current default is not using lld.
* When USE_CLANG_LLD or LOCAL_USE_CLANG_LLD is true or 1,
  * Use *GLOBAL_LLDFLAGS instead of *GLOBAL_LDFLAGS.
    GLOBAL_LLDFLAGS should call lld and with correct lld flags.
  * set my_pack_module_relocations to false.
