# LTO is disabled because the NDK compiler is not necessarily in-sync with the
# compiler used to build the platform sysroot, and the sysroot includes static
# libraries which would be incompatible with mismatched compilers when built
# with LTO. Disabling LTO globally for the NDK sysroot is okay because the only
# compiled code in the sysroot that will end up in apps is those static
# libraries.
