# We support api level 14, but api level 21 is required to build llvm. To
# overcome this problem we use a ndk with api level 21 to build llvm and then
# switch to a ndk with api level 14 to complete the build. When the linker is
# invoked there are missing symbols (like sigsetempty, not available with api
# level 14), the default linker behavior is to generate an error, to allow the
# build to finish we use --warn-unresolved-symbols. Note that the missing
# symbols does not affect std, only the compiler (llvm) and cargo (openssl).
