Clean up the architecture-specific makefiles. Group things appropriately and name each group. Change-Id: I0da45eb0ccde19c31d5e984d0e6eb3dad26630dc

# 32-bit mips.
Reconfig libc's Android.mk to build for multilib 1. Moved arch-specific setup to their own files: - <arch>/<arch>.mk, arch-specific configs. Variables in those config end with the arch name. - removed the extra complexity introduced by function libc-add-cpu-variant-src, which seems to be not very useful these days. 2. Separated out the crt object files generation rules and set up the rules for both TARGET_ARCH and TARGET_2ND_ARCH. 3. Build all the libraries for both TARGET_ARCH and TARGET_2ND_ARCH, with the arch-specific LOCAL_ variables. Bug: 11654773 Change-Id: I9c2d85db0affa49199d182236d2210060a321421

libc_bionic_src_files_mips += \
Clean up forking and cloning. The kernel now maintains the pthread_internal_t::tid field for us, and __clone was only used in one place so let's inline it so we don't have to leave such a dangerous function lying around. Also rename files to match their content and remove some useless #includes. Change-Id: I24299fb4a940e394de75f864ee36fdabbd9438f9

arch-mips/bionic/__bionic_clone.S \
Break bionic implementations into arch versions. DO NOT MERGE Move arch specific code for arm, mips, x86 into separate makefiles. In addition, add different arm cpu versions of memcpy/memset. Bug: 8005082 (cherry picked from commit acdde8c1cf8e8beed98c052757d96695b820b50c) Change-Id: I0108d432af9f6283ae99adfc92a3399e5ab3e31d

arch-mips/bionic/bzero.S \
Fix MIPS build. Warnings are errors for all home-grown bionic code, and the arch-specific code now counts as home-grown bionic code (it was mistakenly counted as "not ours" before). Change-Id: I9c6a881b0dc596bae7dfe112c5c189e073800a3a

Let the compiler worry about implementing ffs(3). It does at least as good a job as our old hand-written assembly anyway. Change-Id: If7c4a1ac508bace0b71ee7b67808caa6eabf11d2

arch-mips/bionic/setjmp.S \
[MIPS] Reimplement syscall to invoke the system call directly Some MIPS kernels do not correctly restart interrupted system calls that have been invoked using the indirect syscall (NR_syscall). The simplest workaround is to handle the indirection in userland and then call the required system call directly. Change-Id: I8385399621529db9a52b463c96925f6decaaca30

[MIPS] Allow united mipsel and mips64el gcc toolchain Explicitly tell 32-bit links that they are doing 32-bit links. This is needed when using united 32-bit and 64-bit toolchains. This is harmless when using older separate 32-only toolchains. Change-Id: I70cbd3f5867e59b1f6f829793444242fb0894aa6
