The native perl's path is not in PATH

[Robert Yang <liezhi.yang@windriver.com>]

The native perl is installed to:

${STAGING_BINDIR_NATIVE}/perl-native/perl

But this isn't in the PATH, so we can use the native perl
by the command "perl" or "#!/usr/bin/env perl".

I wonder why we install the perl to ${STAGING_BINDIR_NATIVE}/perl-native,
but not to ${STAGING_BINDIR_NATIVE}.

It would be good if we can add ${STAGING_BINDIR_NATIVE}/perl-native to the path
or install the native perl to ${STAGING_BINDIR_NATIVE}, I will send a patch
for it if you are ok with it.
