AutoFDO uses a function’s symbol name to look up profile data but
functions with internal linkages do not have globally unique
identifiers. This can lead to name conflicts leading to missing profiles
and performance. We are enabling compiler option
-funique-internal-linkage-names for AFDO builds that will uniquefy
internal linkage symbols making this problem go away.
This CL might regress the performance due to mismatched profiles. It
will recover once we update the profiles.

Write the list of a module's runtime-required libraries to the
`LOCAL_RUNTIME_LIBRARIES` Makefile variable defined for each module.
This enables downstream tools to correctly set up the runtime environment
for execution.

Currently when using sanitizers and building for the device
the -fsanitize= argument is not passed to the linker so that the
linker won't add the runtimes, which have already been added
as explicit dependencies. Pass -fno-sanitize-link-runtime instead
in case the linker has other behaviors when passed -fsanitize=
besides adding the runtimes. Also check for bionic instead of host
so that linux bionic gets the same linker behavior as bionic for
the device.

This will suppress warning like:
system/chre/chpp/app.c:637:3: warning: Call to function 'memset' is insecure
as it does not provide security checks introduced in the C11 standard.
Replace with analogous functions that support length arguments or provides
boundary checks such as 'memset_s' in case of C11

This flag has never done anything for ld.lld, since it has this behavior
by default (and actually can't turn it off either). It's now being
removed as a valid flag from ld.lld, so it's time for Android to drop
the unnecessary flags. See https://reviews.llvm.org/D118942.

In case there are two vendor apexes(one with "use_vndk_as_stable:true",
and the other with "use_vndk_as_stable:false") a VNDK lib used by both
will have "APEX" variant and the former APEX will use "apex" variation.
For example,
apex1(use_vndk_as_stable) -> foo -> libvndk
apex2 -> bar -> libvndk
Since foo, bar and libvndk are mutated into two APEX variations("",
"apex10000"), foo will use the apex variation of libvndk.
To fix this, VNDK libs can use "unique" APEX variations. Then, in the
above example, foo will have "myapex1" variation and libvndk will have
two APEX variations("" and "apex2"). So foo will link to ""(non-APEX)
variation as fallback.

Soong modules that are specific for the host platform (e.g.
java_library_host, cc_binary_host, java_genrule_host, etc.) should
not be built on the target platform (Android), so we add a
target_compatible_with attribute to skip this type of module on an
Android target build.
