Check if the UA32_RELOCATION check is present in Solaris 8

The "your gcc generates UA32_RELOCATIONS" configure test is a major showstopper for Solaris/Sparc users. You have to be very dedicated to getting a Pike to acctually change to source to gcc and recompile it before continuing. Is this bug still present in Sol8, and if so, how does it manifest and can it be worked around in some other way?
