  Log Message:
  -----------
  Drop QEMU_GNUC_PREREQ() checks for gcc older than 4.1

We already require gcc 4.1 or newer (for the atomic
support), so the fallback codepaths for older gcc
versions than that are now dead code and we can
just delete them.

NB: clang reports itself as gcc 4.2 (regardless of
clang version), so clang won't be using the fallbacks
either.
