Subject: base/perlnative/pythonnative/gzipnative: Add a new variable to enable
 easier handling of native path issues

If something is listed in ASSUME_PROVIDED but also manually built (like bzip2-native and
bzip2-replacement-native), we need to ensure that the installed binaries are only accessed
for things which list the provider in DEPENDS.

This patch adds a generic mechanism to handle this instead of everything reinventing the
wheel. EXTRANATIVEPATH += "perl-native" will ensure that ${STAGING_BINDIR_NATIVE}/perl-native
is added to PATH.

This means that:

a) Such providers should install to ${bindir}/xxx-native
b) Should PROVIDE += "xxxx-replacement-native"
c) That users should DEPEND on xxx-replacement-native and have EXTRANATIVEPATH += "xxx-native"

This patch enables this at the core level, the bzip2 recipe still needs adjusting to work
like this along with adjustment of the users of bzip2-replacement-native (python-native?).
