egcs and glibc 2.1

[H.J. Lu]

I have managed to compile egcs with the latest glibc 2.1. I have
to patch both glibc 2.1 and egcs to do that. I have sent my
glibc 2.1 patch to the glibc mailing list. Basically I use
an unused field in _IO_FILE to record the vtable offset since
the new _IO_FILE is bigger than the old one. There is some overhead
in glibc. But it seems work fine with iostream in egcs.
