Any help/hint appreciated,
You don't have cross-built C library installed. Building a cross toolchain from scratch is an intricate process, it is not building just the compiler, you also need bintutils, C library headers and C library itself.
I have never fully understood why the "totally from scratch target" is
the first many people are trying
when there are existing targets for crosstoolchains. My own '$sysroot's
for the 'arm*-linux-gnueabi'
targets in my laptop are :
host-arm-angstrom-linux-gnueabi:
host-arm-cs2009-linux-gnueabi:
host-arm-cs2011-linux-gnueabi:
host-arm-debian-linux-gnueabi:
host-armel-debian-linux-gnueabi:
host-arm-linux-gnueabi:
host-arm-tizen-linux-gnueabi:
host-armv5tel-redhat-linux-gnueabi:
host-armv7hl-redhat-linux-gnueabi:
host-armv7l-tizen-linux-gnueabi:
(there are many more for old MeeGo, Scratchbox etc distros in my desktop
PC) Built just for a fun.
For instance built to try newer GCC releases than the one in the current
Tizen-2.2.1
SDK :
[root@HP-Pavilion bin]# ./arm-linux-gnueabi-gcc -v
Using built-in specs.

Furthermore as an old Unix guy I have never liked the current bloat in
names like here :
--prefix=/build/build_server/rsa/jobs/1261/temp/install-arm-linux
and
--with-sysroot=/build/build_server/rsa/jobs/1261/buildroot/platforms/tizen2.2/rootstraps/tizen-device-2.2.devel
Prefering simpler and much shorter names like :
--prefix=/opt/cross
and
--with-sysroot=/opt/host-arm-tizen-linux-gnueabi
Nothing should disable one to try first crosstoolchains for some
existing target like Tizen. for instance
gcc-4.6.x, gcc-4.7.x, gcc-4.8.x, gcc-4.9.x for that. The previous
Linaro-made toolchain could give some
hints for configuring the self-made GCCs... Like I shamelessly did :
[root@HP-Pavilion bin]# arm-tizen-linux-gnueabi-gcc-4.8 -v
