Why cant the following be defined as processor specific e_flags (like
other processors do) in elf.h itself?
It is easy to exhaust the space of EF_* flags. In sparc this happened
many years ago, so we had to start using the tags Tag_GNU_SPARC_HWCAPS
and Tag_GNU_SPARC_HWCAPS2 to denote hardware capabilities.
