[OE-core] [PATCH 1/3] cpan-base.bbclass: avoid using immmediate assignment for PERLLIBDIRS

[Robert Yang]

The immediate assignment:
PERLLIBDIRS := "${@perl_get_libdirs(d)}"

may cause PERLLIBDIRS get wrong values when multilib, for example, when
the default target arch is x86_64 (/usr/lib64), and mutilib is lib32
(/usr/lib), the ":=" would cause lib32-BPN's PERLLIBDIRS to be
/usr/lib64, and lead to build errors.
