libm: add fmal long double stub

PS2: Fix dependencies

Summary:
This is needed in some target cases, and has since been fixed internally in the AOSP.

From enh@google.com regarding this change:
you were right, and this was the way we should have done it, but i didn't work that out until i fixed this in the same way as part of the aarch64 work (where the weak reference didn't work).

Make use of new memcpy, tweak settings

Summary:

The new memcpy() is slightly faster than the cortex-strings version,
and fixes the Galaxy Nexus camera issue.

    [ARM] libc: use basic ASM strncat implementation

    Summary:
    This implementation is the naive strncat implementation
    for ARM from netbsd upstream.

    Test Plan: Someone else test please, bench gain is significant with http://repo.or.cz/w/glibc.git/blob_plain/ec901dcf2886cfb81d88f9a63cfcd62b9efe6381:/benchtests/bench-strncat.c (no currently integrated bench, only test which is good with this change).
