libc: add tegra2 TARGET_CPU_VARIANT

Tegra2 is a Dual Cortex A9 without FP neon SIMD

based on 'generic' arm (memcpy, memset)
on cortex-a15 and a8 (strcmp)
and armv7-a (memchr and strlen)

These applets are no more common since recent optimisations

strcpy from cortex-a9
strcat : keep standard one

bionic: call stdio cleanup on exit

As of 61e699a133a4807fe878a6cb0d7190d7c96e21f8, stdio clean up
functions are no longer registered in atexit and must be called
manually via __cleanup.

The issue this fixes is some static binaries linked against bionic
cannot output properly when piped or redirected because the buffer
is not flushed before closing.

This is done by pulling in exit.c (and other dependencies) from
netbsd.
