egcs-970828: Some nits

[Horst von Brand]

- At least with gcc-2.7.2.2.f.2 under Linux, it won't build by 'make': The
  spec file created in .../gcc/ is picked up by gcc (?!), which doesn't
  like it at all. Workaround is to copy gcc's spec in there, and build by
  hand (stage by stage): First stage, then 'rm spec; make spec' and then
  second and third stages. 'make compare' is silent for '-O2
  -fomit-frame-pointer -mpentium' here.
- Line 2201 of ...gcc/invoke.texi contains your address with a single '@'
  in it, makeinfo chokes on that and kills the installation
- It would be nice to install as something like 'gcc-2.8.0' &c, so it
  doesn't kill your setup
- What happened to the ChangeLog files? I've only got .10 and .11 for gcc,
  it seems a lot of history got lost...
- The output of './configure --help' isn't the most helpful ;-)
- Please don't bundle this much stuff into the distributions, you might as
  well assume people are able to get texinfo &c on their own.

OK, let's test this baby some now.  Seems that executables/objects are
somewhat larger than my older gcc with '-O2 -fomit-frame-pointer -m486
-malign-{jumps,loops,functions}=2' (standard kernel compile options),
compared to '-O2 -fomit-frame-pointer -mpentium' on the new one.  At least,
gcc has learned to count malign entities by itself now ;-)
