gcc_AC_EXAMINE_OBJECT

[Richard Henderson <rth at redhat dot com>]

The endianness test fails on Alpha/ELF.  The problem is that 

  sed 's/^[0-7]*[       ]*//
          s/\*/./g
          s/ \\n/*/g

you delete all the spaces at the beginning of the line, then
expect a space before the \n.  As luck would have it, the od
output is like

0000100  \n   e   n   d   i   a   n   :   B   A   X  \n 001 021 001 003

and the rest of the transformation results in

   ....\nendian:B
   AX

being split across a line like that.  Since you're about to
remove all of the spaces completely, I suggest not caring
about the space separator that od emits.  Either that or do
the equivalent of your old "cut" via s/^........//.
