Description

The make-rules/shared-macros.mk file includes these four optimization settings for the Studio compiler:

studio_OPT.sparc.32 =   -xO4
studio_OPT.sparc.64 =   -xO4
studio_OPT.i386.32 =    -xO4
studio_OPT.i386.64 =    -xO4
studio_OPT =            $(studio_OPT.$(MACH).$(BITS))

This file has only one setting for the gcc compiler:

gcc_OPT =       -O3

I'm proposing the addition of four optimization settings for the gcc compiler as well. This will be useful because there are two oi-userland components that require reduced optimization only for 32-bit builds with gcc on the SPARC hardware platform.
