This patch gives OpenBIOS users the ability to specify their own compiler prefix. It can be used by just adding PREFIX=<your prefix> right before the switch-arch command. Example: PREFIX=ppc-elf- ./switch-arch ppc

Any reason why you couldn't simply just add $PREFIX to the end of the "for TARGET in ...." line? And thinking about it further, the name PREFIX itself could be a bit vague so maybe CCPREFIX is a better name?
PREFIX sure could be confused with the installation path prefix.
I like the CROSS_COMPILER variable that the linux kernel and some other projects use.
I do find it inconvinient that it always seems that whatever prefix you specify has gcc appended to it given all my cross compilers have gcc-version at the end of their name. That's just how Debian has generated them for years.
