knochenreiter-buildroot/boot/at91bootstrap/at91bootstrap-1.16-eabi-fix.patch

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.
