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?).

gzip/pigz-native: Install into a prefix to avoid clashing with system binaries Due to the system providing a copy of gzip, we face some issues when we 'shadow' that copy with our own leading to a varient of race type bugs, and issues for example if a dependency such as libz is missing but the binary is still present. We usually rely on our dependency logic to protect us from this but for gzip, we don't have this protection since its not listed by all its users (and doing so would be impractical). This patch installed pigz and gzip into their own directory which we only add to PATH when we explictly want these binaries in much the same way we do with perl-native. This means dependency logic is correct when we use the binary and everything should work well. The patch adds an explict dependency into image.bbclass since the accelerated speed of compression is most appreciated at rootfs time.
