Fix assembler error using newer toolchains.
Fixes a ".size expression for pow does not evaluate to a constant" assembler error using linaro 4.7.x.
bionic: Add workarounds for current compilers

With current compilers, we're getting "this function cannot be inlined"
errors on vsnprintf and strlcpy because the always_inline attribute is
set.

Before marking this a "fix" instead of a "workaround", we should figure
out why the functions can't be inlined.

libm: Add a proper sincos() implementation

Add a proper sincos() implementation that unifies the common
calculations for sin and cos instead of running them twice.

This should cause a speedup even in code not using that
(fairly uncommon) function because gcc can optimize separate
sin() and cos() calls into sincos() calls.

bionic: Add ARMv7 optimized string handling routines

linker: add -Wl,--exclude-libs,ALL to LDFLAGS

The linker is essentially a shared library, and incorporates
it's own copy of libc. Even though it's unnecessary, currently
/system/bin/linker is exporting various libc symbols (only to
apps which explicitly dlopen /system/bin/linker)

Add --exclude-libs,ALL, which tells the static linker to mark
all of the imported libc symbols as hidden. This reduces the
size of /system/bin/linker from 92K to 67K with no obvious
loss in functionality.

  $ adb shell ls -l /system/bin/linker
  -rwxrwxrwx root     root        92260 2013-01-16 16:52 linker

  $ adb shell ls -l /system/bin/linker
  -rwxrwxrwx root     root        67660 2013-01-16 16:49 linker

Start cleaning up libm.

We have two copies of fenv.h for every architecture, one of which
isn't used. We also have unused makefiles and files for architectures
we don't support.

This patch removes all the obviously useless files.

Rewrite <fenv.h> for ARM.

The old code was one big no-op.
