[ABE] [erwin@centos62vm os]$ ls -l /bin/sh
lrwxrwxrwx. 1 root root 4 Jan 25 13:43 /bin/sh -> bash

GNU bash, version 4.1.2(1)-release (x86_64-redhat-linux-gnu)

It occurred during building a ARM toolchain. At some point it does some 
magic with a whole load of include files, and those files are passed 
with their absolute path name.

I fixed it by shortening the path in the following way;

-PTXCONF_PLATFORM="${PTXCONF_GNU_TARGET}-${PTXCONF_PREFIX_TCID}"
+PTXCONF_PLATFORM="${PTXCONF_GNU_TARGET}"

The path was;
/home/erwin/ABE/projects/arm-tegra2_hardfloat-linux-gnueabi/master/Toolchain/platform-arm-tegra2_hardfloat-linux-gnueabi-gcc-4.6.2-glibc-2.14.1-binutils-2.21.1a-kernel-2.6.39-sanitized/

And now is;

/home/erwin/ABE/projects/arm-tegra2_hardfloat-linux-gnueabi/master/Toolchain/platform-arm-tegra2_hardfloat-linux-gnueabi/

and that seems to make the difference. On a other machine where the 
/home/erwin/ part is longer it fails in the same way with a 
arm-tegra2-linux-gnueabi (without _hardfloat part).

It seems the setup is really stretching the limits of the system. It 
might be an idea to shortening the PTXCONF_PLATFORM part in the 
Toolchain project by default.
