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. 
     1 [ Building gcc-2.95.3 on cygwin yields a compiler that sticks a .exe

     2   on the end of every executable, even if they're linux executable.

     3   This is highly annoying, and causes glibc build failures that look like this:

     4     mv: `.../bin/makedb.new' and `.../bin/makedb' are the same file

     5     make[2]: *** [.../bin/makedb] Error 1

     6     make[2]: Leaving directory `.../gcc-2.95.3-glibc-2.1.3/glibc-2.1.3/db2'

     7 

     8   The mainline solves this with http://gcc.gnu.org/ml/gcc-cvs/2001-04/msg00440.html,

     9   but that doesn't apply cleanly to gcc-2.95.3.

    10 

    11   So, I'm using

    12   http://www.uclinux.org/pub/uClinux/uclinux-elf-tools/tools-20030314/gcc-2.95.3-cygwin-020611.patch

    13   This is the only patch in crosstool that *isn't* suitable for the mainline.

    14   I can live with this patch simply because crosstool does not build

    15   compilers that target cygwin or VAX/VMS. 

    16   If that ever changes, I might need to try applying the real patch.
