[PATCH 2/3] cpukit: Change _COMPILING_NEWLIB to _LIBC for helper functions decls

[Joel Sherrill]

This is OK. Changed in newlib here:

commit 6226bad0eafe762b811c62d1dc096bc0858b0d1a
Author: Mike Frysinger <vapier at gentoo.org>

    change _COMPILING_NEWLIB to _LIBC

    Use the same name as glibc & gnulib to indicate "newlib itself is
    being compiled".  This also harmonizes the codebase a bit in that
    _LIBC was already used in places instead of _COMPILING_NEWLIB.

    Building for bfin-elf, mips-elf, and x86_64-pc-cygwin produces
    the same object code.
