Yes, it should work. arm-elf/include is a preconfigured entry in the
include-files search-path so any header-file placed in arch/atmel can be
included with #include <arch/atmel/xyz.h>.

But at least for the first test it might be better to keep the
header-files (and the at91*_lib if there is one for the SAM7As) in the
project-directory. Keep the filenames as they are. It might save some
work if you update to a new toolchain, updated files from Ateml are
available or if you send your source-code to someone else.
