Status of newlib toolchain targets

[Yaakov Selkowitz]

With the release of binutils-2.25 and newlib-2.2.0, I decided to give 
them a spin with gcc-4.9.2.

The following targets had issues with binutils, which are now fixed in 
git master:

* mep-elf: https://sourceware.org/bugzilla/show_bug.cgi?id=17753
* sh64-elf: https://sourceware.org/bugzilla/show_bug.cgi?id=17755

The following targets failed when building libgcc, newlib, or libstdc++, 
still unresolved:

* avr-elf:  https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64401
* bfin-elf:  https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63681
* cr16-elf:  https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64424
* fr30-elf:  https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64408
* iq2000-elf:  https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64400
* m32c-elf:  https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64403
* mep-elf:  https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64402
* tic6x-elf:  https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63681
* xstormy16-elf:  https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64407

The following targets require patches to newlib:

* several wrt DESTDIR: https://sourceware.org/ml/newlib/2014/msg00812.html
* sparc64-elf: https://sourceware.org/ml/newlib/2014/msg00815.html

The following targets built successfully (after aforementioned binutils 
and/or newlib patches):

aarch64-elf aarch64_be-elf arm-eabi cris-elf epiphany-elf fido-elf
