Please don't start comment lines with stars. And don't start a comment
inside of another comment :-)

REs are easier to read and write if you write them inside {} instead of
inside "".
Whenever you see (^|\n) it should hint you to use newline-sensitive
matching? Like
{(?n)^#define _ARCH_PWR7 1$}
(it makes ^ and $ match the begin/end of lines instead of of the string,
and makes . and similar not match newlines).

An xfail always needs a comment :-)
