can't bootstrap on alphaev67-dec-osf5.0

[Dave Love]

gcc 3.0.1 won't bootstrap on this platform.  It fails configuring
libstdc++ with the errors below.  (There are various other failures
reported in config.log due to #536845808.)

I bootstrapped with

Compaq C V6.4-214 (dtk) on Compaq Tru64 UNIX V5.0A (Rev. 1094)

gcc 3.0 failed similarly also with gcc 2.95, which I haven't tried
this time.  [I understood the problem was already known, so didn't
report it.]
