We want to store the symbol information for all android binaries in a global database.
* We ingest unstripped binaries into the global database
* When we collect address data from device (e.g. instruction pointer address), we want to lookup its symbol information through the global database. The key of the mapping is a unique build id, which is the same between binaries on device (stripped) and unstripped binaries.
After applying this patch, the system.img size increases by 0.0047% (16.3KB).

The transitive symbol resolving causes build breakage when a binary
has indirect dependency on the NDK library.
We only observed such behaviour in the aarch64 toolchain.

Otherwise wrong set of memory/string functions is chosen when building atom
image (in Bionic we have libc/arch-x86/atom/atom.mk). Plus this naming is
consistent with other x86 architectures.

Bug: 18589470
__LP64__ is only defined for 64-bit compilation targets, so this macro
is evaluated as an implicit 0 in the original case. This change makes
it explicit that we only care whether this is actually defined.

No one's using ARCH_AARCH64 or AARCH_MIPS64 yet, and ARCH_PPC was always more
aspirational than real.

Previously, there was one generic definition for each of the
transform-o-to-* functions in definitions.mk, and one target specific
one in each combo/TARGET_*.mk. The generic one was entirely unused,
and the target specific ones were all nearly identical.
Changing anything in these functions was tedious at best, and often
error prone. The differences between any 32-bit arch and its 64-bit
equivalent were restricted to the name of the linker, and the ARM and
MIPS definitions were identical. The few differences between ARM and
x86 looked to be compatibility for an old (ca. 2008) toolchain issue
with --gc-sections, and a bug (LDFLAGS coming first rather than
later).
To simplify things, I've moved the definitions for these out of
combo/TARGET_*.mk and back into definitions.mk. The differences
between ARM and x86 have been scrapped. Anything that really does
still need to be target specific can be handled as I have the linker:
add a TARGET_FOO variable to the given target and then add it to the
generic definition.
