I'm afraid that these cross-tools are named wrong (except mingw, which is
different). Cross-toolchain should inform potential user about processor
architecture it designed for (armv5tejl), target (linux) and binary format (GNU
EABI). I think, that only "unknown" part may be omitted, but I feel that it's
better to rename it to something like "fedora" (not "redhat", as Adam
suggested).

For example, if someone will develop bootloaders for arm-platforms, then he
should obtain two different cross-toolchains. One - for developing Linux kernel
and user-space applications (which is exactly what I submitted) and another -
for developing "bare-metal" applications, such as bootloaders. See these links
for the details:

http://www.codesourcery.com/sgpp/lite/arm/portal/release858?@template=datasheet

That's why we should specify explicitly what exact type of cross-toolchains
we're providing.

I didn't dig into details yet, but it seems that conventional gcc tries to link
by default with libraries and routines, which cannot be used at the boot-stage
(for example, in my case, it tries to link with code for trapping division by
zero). I would like to remind you, that I'm still not an authoritative person
in developing for ARM, so I can be wrong in some particular details.
