 This patch has some obsolete bits:
 
   Makefile.in
     head -1 => sed q
       No longer needed.
       Makefile.in has no more 'head' commands.
 
   configure
     tail -1 => sed -n '$p'
       No longer needed.
       This file has no more 'tail' commands.
     if [ ... -o ... ]
       No longer needed.
       This code has been replaced.
 
 These files have changed a lot.  I eyeballed them for obsolete bits
 such as 'head' and 'tail' but didn't spot anything.
 
 These bits are still relevant:
 
   ltcf-c.sh
     head -1 => sed 1q
       This occurs in a "host=cygwin|mingw" section so I am unable
       to test it at this time.
 
   ltcf-gcj.sh
     head -1 => sed 1q
       This occurs in a "host=cygwin|mingw" section so I am unable
       to test it at this time.
 
   ltmain.sh
     sort +2 => sort -k 3
       This occurs in a "host=rhapsody|darwin" section so I am unable
       to test it at this time.
 
 Since I'm unable to test these, I'm not going to pursue trying
 to merge them.  I may file a gcc PR so that they can pursue this.
 
 I did build and install gdb and run a complete gdb_mbuild.sh with
 textutils 2.1 and _POSIX2_VERSION=200112 on my machine (host
 i686-pc-linux-gnu), so that code path is clean.
 
 Note that if someone adds a new strictly POSIX host, it will likely
 work, because the dirty code is in host-specific code.
