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.

     9 Hi Robert,
    10 
    11 I've attached two patches:
    12 
    13 1/  For crosstool-0.31 which changes the CYGWIN_URL to one which has the
    14 cygwin source archives.  The version of cygwin that is used to build the
    15 cross toolchain has been changed to cygwin-1.5.15-1-src.tar.bz2 since
    16 most of the mirror sites don't seem to have the original archive used.
    17 [created gcc-3.3.2-cygwin-1.5.15-1.dat - dank]
    18 
    19 
    20 2/ The later cygwin source archive fails to cross build with the error:
    21 /opt/crosstool/i686-pc-cygwin/gcc-3.3.2-cygwin-1.5.15-1/lib/gcc-lib/i686-pc-cygwin/bin/ld:
    22 cannot find -luser32
    23 
    24 unless the second patch is applied,
    25
