[Build-common-hackers] Bug#481893: in some cases it is impossible to input options for Makefile.PL

[Dmitry E. Oboukhov]

Package: cdbs
Version: 0.4.52
Severity: normal
Tags: patch

Some  Makefile.PL  disassemble	options  with  the  help  of
Getopt::Std module, meanwhile if options are written in  the
end of command line, they will be ignored (because they must
be declared before arguments).

So the following construction (DEB_MAKEMAKER_USER_FLAGS = -n):

perl Makefile.PL INSTALLDIRS=vendor -n

doesn't work,

but is impossible to receive the working construction

perl Makefile.PL -n INSTALLDIRS=vendor

with the help of cdbs without redefining the variable
DEB_MAKEMAKER_INVOKE

The patch in attach solves this problem.
