Failing to build libstdc++ for xscale-elf target

[Christoph Baumann <cb at sorcus dot com>]

Hello there,

it is mysterious. I already suceeded in building a toolchain (binutils, 
gcc-3.3, newlib-1.11.0) including libstdc++ under Cygwin. When I tried 
to do it again a few weeks later i failed. I have no clue what is 
different this time.

Output of make when the error occurs:

`/cygdrive/e/cb/cygwin-xscale-elf/build/gcc-build/xscale-elf/libiberty'
