I have made some digging.  Oldest compiler I could find is 4.2 which
is quite old (cc: WorkShop Compilers 4.2 30 Oct 1996 C 4.2) and all
series 4 compilers are quite the same.  This old compiler knows -KPIC
-option and I also checked xemacs 21.4 configure and they use -KPIC
almost for every system available (irix/sysv4/unixware/solaris).
/opt/SUNWspro/bin/cc -cflags|grep -i pic
-KPIC           Compile position independent code with 32-bit addresses
-Kpic           Compile position independent code


Next thing is how to detect 64-bit.  Isainfo is quite good for this
and old compilers don't know anything about -xarch=v9 or v9a/v9b.
Only things that change for eg. on xemacs configure when using 64-bit
are size of long and void *

man cc
---clip clip---
v9  Compile for the SPARC-V9 ISA.
v9a Compile for the SPARC-V9 ISA with UltraSPARC extensions.
v9b Compile for the SPARC-V9 ISA with UltraSPARC-III extensions.
---clip clip---

man isainfo
---clip clip---
     -b    Prints the number of bits in the address space of  the
           native instruction set.
     -k    Prints the name of the instruction set(s) used by  the
           operating  system  kernel  components  such  as device
           drivers and STREAMS modules.
     -n    Prints the name of the native instruction set used  by
           portable applications supported by the current version
           of the operating system.
     -v    Prints  more  detailed  information  about  the  other
           options.
