PCH merge bootstrap failure on irix6.2 due to missing ftello/fseeko

[Kaveh R. Ghazi]

Bootstrapping on mips-sgi-irix6.2 after the recent merge yields an
error in stage1 linking cc1 because ftello and fseeko are missing on
that platform.

Irix6.2 does have regular ftell/fseek which we already use elsewhere
in GCC.

I can either apply something like the patch below, or do autoconf
magic to define e.g. fseeko-> fseek only when the o versions are
missing.

What is your preference?

		Thanks,
