Building dev tools for Solaris x86

Hi,
I am at it again trying to build the Dev tools for Solaris x86, and i run
into some issues.. I am searching the code for the flag assignment to the
SunPro c-compilers, which DON'T support the -K thread flag. But somehow it
is always added in when getting to the vmake point in the compilation.
I searched the machineInfo.c file fixing a few definitions in there to get
this far at all.

Any other ideas where the "-K" "thread" is pushed to the cc options?

The error that i get is below.

Thanks for any hints
