[Bug bootstrap/32287] gas version style changed causes warnings with configure

Here's why I didn't remember the patch - I just checked it in, I didn't write
it.

2007-08-23  Brian Sidebotham  <brian.sidebotham@gmail.com>

        * configure.ac (leb128): Modify sed statement to work with any
        binutils version string.
        * configure: Regenerate

That version definitely handles:
as_ver='GNU assembler (GNU Binutils for Debian) 2.18.20071027'

It does not handle:
as_ver='GNU assembler (Linux/GNU Binutils) 2.18.50.0.3.20071102'

This version format is new and is not produced by the FSF binutils.  I assume
it's a result of HJ Lu's Linux binutils after a merge from FSF trunk.

The ld_vers check up higher in the file was changed to handle the new version
format on 2007-09-23.

HJ, Richi, I can find a lot of confused versions of HJ's patch in that thread,
which starts here:
  http://gcc.gnu.org/ml/gcc-patches/2007-09/msg01170.html

Nowhere can I find the actual approval.  The only version which was approved
was safe, but the patch as applied is unsafe.  If you put a .* there, then it
will match any "xx.yy" string anywhere in the version string, including after
the binutils version!  This does not mess up on --with-pkgversion on new
versions of binutils but only because sed will use the shorter match, and the
binutils version comes second.

+       -e 's,^.*[       ]\([0-9][0-9]*\.[0-9][0-9]*.*\)$,\1,p' \
        -e 's,^.*[       ]\([0-9][0-9]*\.[0-9][0-9]*\)[  ].*$,\1,p' \

Note that second line will never match now.

The ld and as tests should be made uniform again but I think that we should go
back to this one:
