Bug: http://b/69933068
- Remove GCC's intrinsic header path so Clang's headers get included.
- Add '-B' with GCC's binary directory so Clang detects the linker.
- Bug: http://b/109759970 - Pass '--allow-multiple-definition' linker
flag to deal with ld.bfd's inability to handle Clang-generated section
names is fixed.
- Bug: http://b/110800681 - lld cannot link Android's Windows modules
yet
Test: m native-host-cross and run adb_test.exe under wine.

Bug: http://b/69970955
With the MinGW prebuilts update (http://aosp/709402), executables get a
runtime dependency on libgcc_s_sjlj-1.dll with both gcc and Clang.
Passing -static-libgcc removes this dependency and is a better option
than having to package an extra dll with executables.
Test: Run gcc-built adb_test.exe under wine

Scudo is a hardened usermode allocator that is part of LLVM's compiler-rt
project (home of the Sanitizers). clang allows for -fsanitize=scudo as a
possible command line option to link the shared Scudo library to a binary.
This patch add Scudo as a potential sanitize option. Scudo is not compatible
with ASan and TSan and will be disabled if either is enabled.
Bug: 72112048
Test: aosp compiled with m -j
Test: local experiment with scudo: true to ensure that a test target
(tombstoned) could be linked with scudo.

Every time the toolchain adds a new warning, we had to suppress the
warning in every external projects that violates it, or disable it
globally -- which we end up doing most of the time since the first
option is way too time consuming.
Add a separate cflags option for external projects and move existing
-Wno-* flags there so that we can enforce better code quality for
internal projects.
TODO: Move more -Wno-* flags to ClangExtraExternalCflags
Test: m checkbuild
