Makefile: Add $(xcompile) to specify where to write xcompile
This file was being written to the root src directory. It is the only file being written to src during a normal build, while all others are being written to $(obj). I added a new variable to allow specifying the xcompile path. This allows generating a single file if building multiple boards. I also moved the default location into $(obj) so we don't pollute the src directory by default. I also cleaned up the generation of xcompile by removing the unnecessary eval and NOCOMPILE check. I also left .xcompile in distclean so it cleans up stale files. Since .xcompile is written into $(obj), `make clean` will now remove it. The tegra Makefiles are outside of the normal build process, so I just updated those Makefiles to point to the default xcompile location of a normal build. The what-jenkins-does target had to be updated to support these special targets. We generate an xcompile specifically for these targets and pass it into the Makefile. Ideally we should get these targets added to the main build.
