[Libguestfs] [nbdkit PATCH 04/10] perl: Ignore -Wshadow warnings
perl.h requires that the user declare a static PerlInterpreter * named
'my_perl', but also shadows this declaration in functions declared
with the XS() macro. As there's no way to avoid this issue, turn off
this warning here so we can fix -Wshadow warnings elsewhere.
