[OE-core] [PATCH] perl: set the perl libraries search path

[jackie.huang at windriver.com]

From: Jackie Huang <jackie.huang at windriver.com>

The default value for this is ../../lib which ends up with
something like:
| ./sysroots/x86_64-linux/usr/bin/perl-native/perl5.20.0.real \
| "-I../../lib" "-I../../lib" "-MExtUtils::Command::MM" -e pod2man \
| "--" --section=0 --perm_rw=644 perldoc.pod blib/man1/perldoc.1

in this case, nativeperl will find libraries from the target build,
When using an x86-64 host to target Haswell, you can end up with
../../lib including precompiled modules which use Haswell
instructions, it fails with:
| Running pm_to_blib for dist/if directly
| Skip ../../lib/if.pm (unchanged)
| Makefile:457: recipe for target 'manifypods' failed
| make[1]: *** [manifypods] Illegal instruction

So set it to use the -native ones instead of those from the target
build.
