I've rebuilt with -pg in the following directories:

  . libiberty
  . bfd
  . opcodes
  . libctf
  . gdbsupport
  . gdb

The profile produced by gprof is attached.  The time information looks
very inaccurate, almost bogus, to me (since GDB ran for more than 2
minutes, I expected to see gdb_main show 130 as the value of
cumulative seconds, but the profile shows only 2.21?).  But
nevertheless I hope the data will be useful.

Let me know if I can provide more information.
