>Environment:
IRIX64 octane 6.5 07202013 IP30
(MIPSpro 7.4.4m on IRIX 6.5.30)
>Description:

According to the mk/defaults/mk.conf file, the correct values for 'ABI' are "64 
(64 bit ABI), 32 (SGI's N32 ABI), undefined (SGI's old o32 ABI)"

However, the update transform-mipspro-cc has:

"
-32             |\
-n32            |\
-64             ) if [ $arg = "-$wrapper_abi" ]; then
                        transform_pass
                else
                        transform_fail "Wrong ABI argument $arg for ABI 
$wrapper_abi."
                fi ;;
"

... which will fail for the most common configuration - n32 (since '-n32' != 
'-32').

There is a mismatch here between what mk.conf expects (ABI='32' for n32) and 
what transform-mipspro-cc expects (ABI='n32' for n32).

Additionally, also in transform-mipspro-cc, when filtering -O options, '-OPT:*' 
should also be allowed.
>How-To-Repeat:

Attempt to build any software with ABI=32 (to enable n32 ABI) on IRIX.
>Fix:

With the mk.conf documentation needs to be updated to state ABI="n32" for n32 
(which would be more obvious, but could lead to regressions), or alter the 
logic in transform-mipspro-cc to treat '-n32' differently from '-32' and '-64'.

(Background: -n32 enables the canonical default ABI for IRIX 6.x; -32 is the 
"old" 32bit ABI which is only used to IRIX 5.x compatibility)
