netbsd-eabi.h was never merged from the now present upstream version.

reduce diffs to upstream here and in other files in this subdir.

remove unused ARM_EABI_UNWIND_TABLES and __UNWIND_TABLES__.

clang defines __UNWIND_TABLES__, but doing this in GCC triggers the
need for more libgcc / libc unwind functionality to be added, and this
code has never been enabled for netbsd/earm.  (could potentially clean
up unused code in libc now, or, revive this once the full support has
been implemented..)
