We usually test against the newlib/libgloss environment, but for a few ports that also support Linux apps, we want to test that logic too. A lot of the C code is written such that it works with either newlib/libgloss or glibc/linux toolchains, but we have some tests that end up being Linux-specific. Cris has been using the target tuple as a rough proxy for this (where cris*-*-elf is assumed to be newlib/libgloss, and everything else is glibc/linux), but that is a bit too rough, and it doesn't work in a multitarget build. So lets create a few stub files that we can do compile tests with to detect the different setups, and then let tests declare which one they require (if they require any at all).
