platform_ToolchainOptions: Add check for libgcc_s/libstdc++.
As part of migration to llvm based libraries, we want to
prevent new dependencies on libgcc_s/libstdc++. Add a new check
to platform_ToolchainOptions to do so.
Whitelist any current users e.g. binaries delivered from outside,
or built using gcc.
BUG=chromium:811121
