Thanks all for your help...and I know why now mmx flag was getting masked. Its in the use.mask as suggested by Martins.
Attached is the use.mask file i have ...that file gets updated/overwritten every time i do a "emerge --sync", right ? For some reason all the flags under x86/amd are uncommented... when i comment them out then emerge --info shows me mmx etc... For now i can live with commenting them out. But I did not realize i had to do that...i never had to do this before on other machines (not amd64 though...x86 and ppc64). regards Kumar
