t/linux: use toolchain and platforms

This allows us to do builds for different platforms consistent with how
Bazel does them. Also uses our own LLVM toolchain instead of the
"ambient" GCC. As bzImages only exist for x86, rename everything to
Image which is the cross-platform name. For us this is fine as we use
the PE entry point which exists for all of these.

Binary path generation is a hack as not all of the ones Linux needs are
actually available in the rules-based toolchain and we need a special
calling convention to work around a bug in LLVM when compiling assembly
with preprocessor macros.
