Sure, but it makes the mess even worse.  You should instead:

- in config/t-svr4, change the two CFLAGS assignments to use +=
- in config/i386/t-sol2, change the CRTSTUFF_T_CFLAGS assignment to "+= 
-O2" and remove the TARGET_LIBGCC2_CFLAGS assignment
- in config.gcc, change

           tmake_file="t-sol2 i386/t-sol2 t-svr4"

to

           tmake_file="${tmake_file} t-sol2 i386/t-sol2 t-svr4"

and move it at the end of the case stanza, i.e. before

           ;;
   i[34567]86-*-sysv5*)           # Intel x86 on System V Release 5
