Update from version 2.010800nb1 to 2.010801.

Pkgsrc changes:
o Re-do patch-ab so that the tests and adaptations for the various
  NetBSD archs don't sit inside "if ($os eq 'sunos')" (!).

Upstream changes:

2.010801:
  build_paricfg() takes a version argument
  write_paricfg(): likewise.
  Emit paricfg.h which supports GP/PARI v2.3.4.
  Remove the section on CPAN mirroring from README.
  INSTALL: Explain how to google when server is down.
  Skip another subtest in ploth.t.
  Fix treatment of -oo in tests.  Still fails, but now with
    not ok 12 # in='intmellininvshort(2,4,$tab)-$A'
    #    out='-3.364954880E-97+9.90717831E-100*I', type='Math::Pari'
    # pari==='-3.072350108 E-97 + 9.90717831 E-100*I'
    # re_out='\-3\.072350108,?\s*E\-97,?\s*\+,?\s*9\.90717831,?\s*E\-100\*I'
  Consider `intfuncinit' as requiring "unsane" precision of limits
(bug in GP/PARI???).  Now all tests pass???
