Brandon Casey efe47f8f2c perl/Makefile.PL: detect MakeMaker versions incompatible with DESTDIR
It appears that ExtUtils::MakeMaker versions older than 6.11 do not
implement the DESTDIR mechanism.  So add a test to the generated perl.mak
to detect when DESTDIR is used along with a too old ExtUtils::MakeMaker and
abort with a message suggesting the use of NO_PERL_MAKEMAKER.

$(error ExtUtils::MakeMaker version "$(MM_VERSION)" is older than 6.11 and so \
is likely incompatible with the DESTDIR mechanism. Try setting \
NO_PERL_MAKEMAKER=1 instead)
