README: Remove outdated information

Documentation tends to get outdated, and "Newly added" does not age well.

Remove descriptions of toolchain problems that were fixed ~20 years ago.

-This does not mean that libunwind cannot be used with older compilers
-or C libraries, it just means that for certain corner cases, unwinding

-Note: If you get lots of errors in `Gia64-test-nat` and `Lia64-test-nat`, it's
-almost certainly a sign of an old assembler.  The GNU assembler used
-to encode previous-stack-pointer-relative offsets incorrectly.
-This bug was fixed on 21-Sep-2004 so any later assembler will be
