  -----------
  [libc] add printf hexadecimal float conversion

This patch adds the %a/A conversions to printf, as well as the compiler
flag to disable floating point handling entirely. This will allow our
printf implementation to display every type of argument allowed by
printf, although some formats are still incomplete.
