perl5.000 patch.0j: fix minor portability and build problems remaining even after patches 0a through 0i

Specifically, here's what's included:

Configure
        Regenerated with metaconfig patchlevel 50.  This changed
    a variety of things, mostly related to selecting and changing
    the installation prefix.
        Handle csh, sed, and byacc no matter what the setting of
    d_portable.  (This was causing glob problems in patch.0i).
        Set d_portable to default to 'y'.  It doesn't matter anyway,
    but gives people a warm fuzzy feeling.
        Remove useless d_group and d_passwd tests.
        Add check for <sys/stat.h>.
        Improve & generalize AIX version detection.
        Consider /opt/man/man1 as a possible place to install man pages.
        Be a little more robust about OS version changes when deciding
    if the output of uname -a has really changed.
  
MANIFEST
MANIFEST.new
        Added hints/mpeix.sh.

README
        Tell users the Configure defaults are probably right.

Makefile.SH
        Better detection of whether user has byacc.
        Use $(MAKE) instead of make.

U/Loc_sed.U
        Works again with d_portable='define'.

U/Myinit.U
        Set d_portable=define as default.

U/d_byacc.U
        Detect whether user has byacc even if d_portable=define.

U/d_csh.U
        Works again with d_portable='define'.

U/d_group.U
        Empty file to avoid useless metaconfig test.
        
U/d_passwd.U
        Empty file to avoid useless metaconfig test.

U/dist.patch
        This file contains two minor updates to dist3 PL50 that were used
    to generage Configure.

U/i_sysstat.U
        New test.  See if sys/stat.h is available.

config.H
        Updated.

config_h.SH
        Updated to metaconfig patchlevel 50.

ext/NDBM_File/Makefile.PL
ext/ODBM_File/Makefile.PL
        Add -lucb for SVR4 systems.

handy.h
        Protect agains g++-2.6.3, which predefines bool.  g++ can be
    used to compile an extension, but not perl itself.  Still, the
    extension will #include "perl.h", which eventually gets
    "handy.h", which #define's bool.  If this happens to you, add
    -DHAS_BOOL to your ccflags in your extension, or else ensure that
    _G_config.h is #include'd before perl.h.  (_G_config.h will define
    _G_HAVE_BOOL, if indeed your version of g++ has bool.)

hints/aix.sh
        Updated.  Handles AIX 3.2.x and 4.1.  Comments included!

hints/hpux_9.sh
        Updated.
hints/irix_4.sh
        Updated.   Includes comments for IRIX 4.0.4

hints/linux.sh
        Updated.  Beginnings of ELF support added, but completely
    untested.

hints/mpeix.sh
        New hint file.

hints/solaris_2.sh
        Useless ccflags="$ccflags" line removed.

hints/svr4.sh
        Updated.

installperl
        Doesn't  use Config anymore (it already reads config.sh
    directly.  That's probably backwards, but, oh well.
        Install perl.exp for AIX.

lib/ExtUtils/MakeMaker.pm
        Upgraded from 4.01 to 4.03.

makedepend.SH
        Use $MAKE instead of plain make.

Index: op.c
        Remove overlapping strcpy().

perl.h
        Add test for <sys/stat.h>.
        Delete unused VOIDSIG stuff.
        Delete unused   typedef struct lstring Lstring;

perl_exp.SH
        Add safexxxx calls.

pp_sys.c
        Delete wayward break in HAS_ALARM section.

proto.h
        Change true and false (!) in function prototypes to please
    g++-2.6.3, which has true and false built in.  (See notes for
    handy.h.)

Index: unixish.h
        Long-overdue housekeeping.
        HAS_GROUP and HAS_PASSWD are always defined.

util.c
        Yet another (char*) cast for bcmp.

vms/config.vms
        Changed comments to match unixish.h.

writemain.SH
        Now correctly handles nested static extensions.  Recent
    MakeMakers have moved where they get built.

x2p/a2p.h
        More definitions that will doubtless cause trouble somewhere
    else.

x2p/a2py.c
x2p/walk.c
        Remove unprotected  char *strchr();
