libc/uClibc: fix building on system with recent glibc

While trying to build a toolchain with ct-ng 1.5.0,
arm-unknown-linux-uclibcgnueabi target,
I get the following error:

[INFO ] Installing C library headers
[EXTRA] Copying sources to build dir
[EXTRA] Applying configuration
[EXTRA] Building headers
[EXTRA] Installing headers
[ERROR] extra/scripts/unifdef.c:209: error: conflicting types for 'getline'
[ERROR] make[2]: *** [extra/scripts/unifdef] Error 1
[ERROR] Build failed in step 'Installing C library headers'

The following patch solves the problem.
(It's a backport of this uClibc commit:
http://git.uclibc.org/uClibc/commit/?id=49e81cada73616864b9b31df0aeb6961c30f5a6e
)

[--SNIP from another mail--]
AFAIK this is a problem since glibc 2.10.

     6     Newlib is a C library intended for use on embedded systems. It is a 

     7     conglomeration of several library parts, all under free software 

     8     licenses that make them easily usable on embedded products. Newlib 

     9     is only available in source form. It can be compiled for a wide 

    10     array of processors, and will usually work on any architecture with

    11     the addition of a few low-level routines.

    39       If you do native AVR32 development you want to say 'Y' here.
