Add a gdbarch 'print_auxv_entry' method for FreeBSD ABIs.
Add a 'print_auxv_entry' method for FreeBSD ABIs that parses
FreeBSD-specific auxiliary vector entries and outputs a suitable
description using fprint_auxv_entry.
gdb/ChangeLog:
* fbsd-tdep.c: Include "auxv.h".
(fbsd_print_auxv_entry): New function.
(fbsd_init_abi): Install gdbarch "print_auxv_entry" method.
