3606 Different packaging systems have different levels of native Multilib 3599 Generic implementation details as well as details that are
3607 support. 3600 specific to package management systems exist.

3604 <listitem><para>The typical convention used for the

3609 that contain <filename>${PN}</filename> have
3610 <filename>${PN}</filename> at the start of the name.
3611 When that convention is not followed and

3619 (e.g. "-pokymllib32" for a "lib32" Multilib with
3620 Poky).
3621 The reason for this slightly unwieldy contraction
3622 is that any "-" characters in the vendor
3623 string presently break Autoconf's
3624 <filename>config.sub</filename>, and
3625 other separators are problematic for different
3626 reasons.
