./configure --host=arm-none-eabi fails with current arm gcc toolchain

[sdrsdr]

barematal toolchains such as arm-none-eabi do need alot of tweaking to get to create executables and one of this tweak is providing a minimalistic libc that should not depend on the compiler being able to create executables especially one referencing _exit symbol in them :)

c:/cygwin/opt/armtoolchain/bin/../lib/gcc/arm-none-eabi/6.3.1/../../../../arm-none-eabi/lib\libc.a(lib_a-exit.o): In function `exit':
exit.c:(.text.exit+0x2c): undefined reference to `_exit'
