This fixes the issue with LibraryMake and OpenSSL/Auth::PAM::Simple/etc
(if LibraryMake was installed as a dependency of the above, the build
would fail the first time, but not the second)
Add our current destdir to @*INC
Is it tested that this does not break rebootstrapping? Because one important thing about rebootstrapping panda when rakudo was reinstalled is that we do not pick now outdated precompiled modules.
I rebootstrapped (without updating rakudo) after this change with no issues. It looks like bootstrap should be fine anyway, since this adds to the end of @INC, while bootstrap.pl adds to the beginning, so the bootstrap folders will be checked before the new @INC folder.
Looks good to me :)
