Is it only powerpc that needs this symbol?

It appears that MIPS needs it too for NPTL and I guess that most/all archs will need
it.

I think that __libc_stack_end needs to be impl. in uclibc, the NPTL
http://uclibc.org/cgi-bin/viewcvs.cgi/branches/uClibc-nptl/ldso/ldso/dl-startup.c?rev=10461&view=auto 
branch already have it.
