Jeffrey Zhang 581ffa023b Support non-x86_64 DIB_DISTRIBUTION_MIRROR variable for CentOS 7
Other architectures are stored under "altarch" for CentOS 7, update
the match.

Convert the delimiters to "," to avoid a subtle problem with "|" --
POSIX states

  Within the BRE and the replacement, the BRE delimiter itself can be
  used as a literal character if it is preceded by a backslash.

So "s|\(foo\|bar\)|moo|" doesn't do what you might think; the inner
pipe becomes a literal | and this will *not* match "foo" or "bar".
