Ada bootstrap failures on various platforms

[Rainer Orth]

I've just started bootstraps of current mainline on several platforms and
ran into Ada bootstrap failures almost everywhere (only alpha-dec-osf* is
ok so far):

* sparc-sun-solaris2.8:

Bootstrap comparison failure!
ada/a-elchha.o differs
[many more, omitted...]
ada/usage.o differs

  Here's the diff between the stage2 and stage3 versions of usage.s:

  So the changes are primarily just label renumberings.

* i386-pc-solaris2.10:

raised CONSTRAINT_ERROR : @qèW

* mips-sgi-irix6.5:

ada/usage.o differs

  The usage.s changes are similar to sparc:

My last bootstraps are almost a month ago, so I'd have to start tracking
down what change caused this.  I anyone else seeing similar Ada comparison
failures?
