Define HANDLE_PRAGMA_PACK_PUSH_POP on FreeBSD

[Gerald Pfeifer]

This brings FreeBSD in line with NetBSD, GNU/Linux and some others
and addresses the following two testsuite failures:

  < FAIL: g++.dg/cpp/_Pragma1.C (test for excess errors)
  < FAIL: gcc.dg/cpp/_Pragma6.c 

Tested on i386-unknown-freebsd6.3 without any other changes in terms
of testresults.

Okay to apply to mainline and GCC 4.3?
