Remove obsolete information about Perl

[Russ Allbery <rra@stanford.edu>]

The problem compiling Perl mentioned in the External Bugs section of
gcc.texi is fixed in Perl 5.004 and 5.005, isn't present in Perl 4.036
(the final released version of Perl 4), and from evidence in the Perl hint
files, appears to have been fixed sometime before Perl 5.001m, which makes
it rather ancient.  Someone would really have to work to acquire a copy of
Perl with this bug these days.

I propose this patch to remove this item, to avoid needless confusion.
(If not this, then at least some note should be added saying that this
problem doesn't apply to current versions of Perl.)

-If you have trouble compiling Perl on a SunOS 4 system, it may be

-typing @samp{./doSH; make depend; make}.

 On various 386 Unix systems derived from System V, including SCO, ISC,
 and ESIX, you may get error messages about running out of virtual memory
 while compiling certain programs.
