Back-port 5.0 fix to 4.1.  Fix Bug#27294 by using trx returned by
check_trx_exists() instead of prebuilt->trx. This has been fixed in 5.1 in
r782.

      
      test_if_data_home_dir fixed to look into real path.
      Checks added to mi_open for symlinks into data home directory.

Bug#33976: buffer overflow of variable time_buff in function com_go()

An internal buffer was too short.  Overextending could smash the 
stack on some architectures and cause SEGVs.  This is not a problem
that could be exploited to run arbitrary code.

To fix, I expanded one buffer to cover all the size that could be
written to (we know the abolute max).


client/mysql.cc:
  Bump up the max size of the time-elapsed buffer displayed at the end
  of queries.

Fix the code to get the "libgcc" file name so that the failure of Intel's ICC
to provide this information does not cause any problems.

This fixes  bug#33536  Option "--print-libgcc-file" does not work with ICC compiler


scripts/make_binary_distribution.sh:
  The (old) code to get the "libgcc" file name does not really work when using Intel's ICC.
  ICC accepts the "--print-libgcc-file" option but ignores it, does not produce any output.
  
  However, ICC tricks automake into taking it for a GCC ("GXX" variable is set, see
  http://www.gnu.org/software/autoconf/manual/html_node/C_002b_002b-Compiler.html#C_002b_002b-Compiler
  and its discussion of the "AC_PROG_CXX" macro).
  
  There are two possible approaches:
  a) Check "$CC" or "$CXX" to tell ICC from GCC, and do not ask ICC for the "libgcc" file name.
  b) Just ask it, but protect that code so that its failure does not cause any damage.
  
  This patch takes the second route:
  1) Put the call "@CC@ ... --print-libgcc-file" into a pipeline, followed by "|| true",
     so that (for the shell semantics) the command cannot fail.
     (ICC will exit non-zero because it is not given a source file.)
  2) Explicitly redirect any error messages.
  3) Do not use the compiler's return code but rather the (non)empty variable to check success.
  4) Ensure that the contents really is a file before taking it as a file name.
  
  Item 1) is especially important when the tool gets a "set -e" (this happens in 5.1, currently)
  which would make the failing compiler call a fatal thing.
  
  This fixes  bug#33536  Option "--print-libgcc-file" does not work with ICC compiler
