971122 won't build on alphaev56-unknown-linux-gnu

Hi all.

When I try make bootstrap of egcs-971122, it fails in the build of gcc towards
the end of the stage1 build as it makes enquire.  Specifically, as gives
me the following errors:

  /tmp/cca16618.s: Assembler messages:
  /tmp/cca16618.s:666: Error: macro requires $at register while noat in effect
  /tmp/cca16618.s:679: Error: macro requires $at register while noat in effect
  /tmp/cca16618.s:689: Error: macro requires $at register while noat in effect
  [ad nauseum]

The offending lines of assembler are things like

   ldbu $2,0($1)

or 

   ldwu $3,32($15)

Diffing the assembler produced by 971122 with 971114 gives (for line 666)

This is on an alpha Miata, with glibc-2.0.5c, bootstrapping 971122 with
egcs-971114.

egcs configured with:
  env CC=/usr/local/egcs/bin/gcc CXX=/usr/local/egcs/bin/g++ CFLAGS=-O2 \
      CXXFLAGS=-O2 ./configure --prefix=/usr/local/egcs

Anyone else seen this?
