Anything with the 'xscale-elf' support...

 The '--with-newlib' is obligatory when using 'newlib' as the target C 
library!  If you
have your own custom/proprietary C library for 'xscale-elf', then that 
should be
preinstalled before starting the configure&build!  The '--with-newlib' 
should  remove
all the link tests against the existing target C library from the extra 
'lib*' configures,
the 'libstdc++-v3' being one. Your  error seems to come from the 
libstdc++-v3
configure...

What was the GCC version tried?   The new gcc-4.1.1 seems to require the 
'--disable-shared'
for instance with ARM, otherwise it tries to link against the "created" 
'libgcc_s.so.1' despite
of using the '--with-newlib'.  A stupid bug and a stupid workaround 
('newlib' neither the target,
'xscale-elf', don't support shared libraries).  With the gcc-4.1.1 also 
the '--disable-shared' is
obligatory...
