Handle FreeBSD-specific AT_EHDRFLAGS and AT_HWCAP auxiliary vector types.
FreeBSD recently added two additional ELF auxiliary vectors. FreeBSD's
AT_HWCAP uses a different number compared to AT_HWCAP on Linux as the
numerical value was already in use for a different vector on FreeBSD.
include/ChangeLog:
* elf/common.h (AT_FREEBSD_EHDRFLAGS, AT_FREEBSD_HWCAP): Define.
gdb/ChangeLog:
* fbsd-tdep.c (fbsd_print_auxv_entry): Handle AT_EHDRFLAGS and
AT_HWCAP.
