patch for toplev.c bootstrap failure mainline on x86_64-linux

[Andreas Jaeger <aj at suse dot de>]

Geoff' latest pch patches fail to bootstrap:

/usr/src/aj/cvs/gcc/gcc/toplev.c: In function `default_pch_valid_p':

/usr/src/aj/cvs/gcc/gcc/toplev.c:4206: warning: assignment discards qualifiers from pointer target type
make[2]: *** [toplev.o] Error 1

The following patch fixes the failure, committed as obvious after
testing compilation.  I'll do a complete bootstrap now,
