The Makefile must run makedef.pl with -Ilib on the command line

It can't rely on adding 'lib' to @INC in a BEGIN block because during the
build not all modules *are* in lib yet. For miniperl the two are not
equivalent - adding -Ilib means that lib/buildcustomize.pl is run, and this
sets up @INC properly to include all the toolchain modules in dist and cpan.

In particular, constant is dual life and hence not available as
lib/constant.pm until it has been copied from dist/constant/lib as part of
the build process. Hence with a parallel build on AIX, before this commit
there was a race condition between the job that builds dist/constant and the
job that builds perl.exp. Sometimes the race was lost, resulting in a
mysterious failed build.

All other users of makedef.pl already invoke it with the appropriate -Ilib
or -I..\lib, so this change won't affect them.
