a0ee07829a Upgrade libm.
This brings us up to date with FreeBSD HEAD, fixes various bugs, unifies
the set of functions we support on ARM, MIPS, and x86, fixes "long double",
adds ISO C99 support, and adds basic unit tests.

It turns out that our "long double" functions have always been broken
for non-normal numbers. This patch fixes that by not using the upstream
implementations and just forwarding to the regular "double" implementation
instead (since "long double" on Android is just "double" anyway, which is
what BSD doesn't support).

All the tests pass on ARM, MIPS, and x86, plus glibc on x86-64.

ae5c64413b Add dependencies on all the makefiles.
This should help prevent broken builds next time I'm messing with
assembler/compiler/linker flags...

70b1668a76 remove obsolete SuperH support
We don't have a toolchain anymore, we don't have working original
kernel headers, and nobody is maintaining this so there is really
no point in keeping this here. Details of the patch:

- removed code paths from Android.mk files related to the SuperH
  architecture ("sh")

- removed libc/arch-sh, linker/arch-sh, libc/kernel/arch-sh

- simplified libc/SYSCALLS.TXT

- simplified the scripts in libc/tools/ and libc/kernel/tools

ddd235bd9c Add sincos() and sincosf() implementation.
This is a GLibc-compatibility patch required to simplify our
upcoming toolchain work/porting.
