undefined reference to C++ constructs in libppl when linking cc1-dummy.exe

[Doug Crawford <dcraw101 at yahoo dot com>]

I am using crossstool-ng 1.8.1 built and hosted on cygwin and targeting powerpc 
linux uclibc.? It successfully builds libbackend.a then tries to link 
cc1-dummy.exe but that step generates a lot of errors related to undefined 
references to exception handlers and other C++ standard library stuff in 
libppl_c.a.? When linking cc1-dummy.exe I see that that the link tool is 
i686_build_pc_cygwin_gcc.? If libppl_c.a contains c++ constructs shouldn't the 
link too be i686_build_pc_cygwin_g++?? I have included the relevant error from 
the log.? The complete log is here: http://pastebin.com/Ugsy55a5
