Read this article http://wiki.embeddednirvana.org/Building_your_own_toolchain. A brief given a brief about explanation on instruction set and cross compile target is given.
It is highly recommended that you use the toolchain supplied from the chip manufacturer since it would be optimised for the chip you are using. A program compiled for ARM7 can run perfectly well on arm11 arch, but then you won't be able to utilize h/w features of the arm11 arch.
As for the complete list, it's available on gcc's site http://gcc.gnu.org/onlinedocs/gcc/ARM-Options.html

I believe there's a hero in all of us
who keeps us honest, gives us strength, makes us noble, and finally allows us to die with pride,
even though sometimes we have to be steady, and give up the thing we want the most... even our dreams.
