execvp: /bin/sh: Argument list too long while building glibc 2.5 with crosstool-ng

Question

I am trying to upgrade our build server from opensuse 9 to ubuntu 14.04. Our target operative system is uClinux with kernel 2.6.24 and glibc 2.5 and gcc 4.2.1. We are using crosstool-ng for building our cross toolchain. Building toolchain is working fine and it is possible to build the kernel as well. But when building the glibc in nptl, the build is exiting with make Error 1.

I am seeing just one error which repeats:

make[4]: execvp: /bin/sh: Argument list too long

In some posts like this one or this one it seems that the problem is the maximum size of strings passed to execve system call. However what is starnage is that when on our old opensuse I am running: getconf ARG_MAX then the answer is 131072, while on the ubuntu 14 the answer is getconf ARG_MAX which is much bigger. and in the same way running cat /proc/$$/environ | wc -c on opensuse whill give 482 as answer while the answer on ubuntu is 1257. When I am moving the glibc folder to a folder with shorter path, then build works without problem. I wonder if this is the real problem and if there is a solution for this. The make file I am using for building glibc is:
