at91bootstrap: switch to the official version

The Buildroot makefile was fetching and building the special
AT91Bootstrap of Ulf, which is not the Atmel official version. While
Ulf's variant has a better configuration/build system, the Atmel
version, as officially supported, is probably a better choice for the
future.

The Atmel version only needed a small tweak to work with EABI
toolchains.

+When using an EABI toolchain, the default compilation generates
+references to __aeabi_unwind_cpp_pr0(). This symbol is defined in
+libgcc, but we don't want to use it for a bootloader.
+
+Therefore, this patch passes some additional CFLAGS to disable the
+generation of such references by avoiding unwind tables, exceptions,
+etc.
