Status of newlib toolchain targets

[Yaakov Selkowitz <yselkowi at redhat dot com>]

With binutils-2.25.1, gcc-5.3.0, and newlib-2.3.0.20160226:

iq2000-elf (PR64400), m32c-elf (PR64375), and mep-elf (PR64402) still do 
not build; the latter has been declared obsolete.

arm-eabi newlib requires a small include path fix; will post shortly.

cr16-elf and lm32-elf require a patch to include newlib-stdint.h:
https://raw.githubusercontent.com/cygwinports-extras/cross-gcc/master/5.3-newlib-stdint.patch
(Nick: I see cr16 committed but not lm32?)

frv-elf requires r222519:
https://raw.githubusercontent.com/cygwinports-extras/cross-gcc/master/5.2-frv-r222519.patch

m32r-elf requires r226445:
https://raw.githubusercontent.com/cygwinports-extras/cross-gcc/master/5.2-m32r-attributes.patch

moxie-elf binutils requires some post-2.25 commits:
https://raw.githubusercontent.com/cygwinports-extras/cross-binutils/master/2.25-moxie-opcodes.patch

v850-elf requires a patch to remove a feature added to binutils 
post-2.25, and a backport of r232451:
https://raw.githubusercontent.com/cygwinports-extras/cross-gcc/master/5.2-v850-msoft-float.patch
https://raw.githubusercontent.com/cygwinports-extras/cross-gcc/master/5.3-v850-PR65501.patch

With the above fixes, the following targets build successfully:

aarch64-elf aarch64_be-elf arm-eabi bfin-elf cr16-elf cris-elf 
epiphany-elf fido-elf fr30-elf frv-elf h8300-elf i386-elf ia64-elf
