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 GCC trunk now has multiple internal headers directories, one
     2 containing the self-contained GCC-provided headers and one containing
     3 the <limits.h> (not self-contained but including libc's <limits.h> or
     4 a fixed version thereof) and the fixed headers; more such directories
     5 may be added in future.
     6 
     7 When glibc uses -nostdinc, it needs to use -isystem options for all
     8 these internal directories.  This patch teaches it about the
     9 include-fixed directory (and is harmless with old GCC versions without
    10 that directory).

    14 	* configure.in: Also pass -isystem option for GCC's include-fixed
    15 	directory.
    16 	* configure: Regenerate.
