commit 996bcb143cb8755cadb986e084b5f24e3ffdb03b
Author: Andre McCurdy <armccurdy at gmail.com>

    bitbake.conf: include ASNEEDED in TARGET_LDFLAGS directly
    
    Previously, ASNEEDED was appended to TARGET_LDFLAGS from
    as-needed.inc via tcmode-default.inc and so may not have been enabled
    for external toolchain builds or other configurations which over-ride
    TCMODE (ie builds which do not include tcmode-default.inc).
    
    Include ASNEEDED in TARGET_LDFLAGS directly from bitbake.conf to
    ensure that the optimisation is applied to all builds (and for
    consistency with the way that TARGET_LINK_HASH_STYLE is handled).
