uninative: Set the dynamic linker to use at compile time
Its possible some dynamic runtime library in the dependency chain may
come from sstate and link to libraries which need the libc from
uninative. If we don't do this and binaries are run at do_install time
they would fail to find the symbols from the later libc. Examples:
cmake-native do_install:
bin/cmake: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.25' not found (required by TOPDIR/tmp/work/x86_64-linux/cmake-native/3.10.3-r0/recipe-sysroot-native/usr/lib/libexpat.so.1)
dbus-native do_install:
tmp/work/x86_64-linux/dbus-native/1.12.2-r0/build/bus/.libs/lt-dbus-daemon: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.25' not found (required by /home/pokybuild/yocto-autobuilder/yocto-worker/nightly-x32/build/build/tmp/work/x86_64-linux/dbus-native/1.12.2-r0/recipe-sysroot-native/usr/lib/libexpat.so.1)
This issue is resolved when the interpreter is changed at sstate unpack
time but this isn't soon enough to avoid issues at compile/install time.
By specifing which dynamic linker/loader to use at compile time, this
race window is removed entirely.
