[PATCH 2/2] rpm: Enable compatibility with older RPM packages that have invalid platforms

[Mark Hatle <mark.hatle@windriver.com>]

Some LSB packages appear to have the platform set to '%{_target_platform}'
which is not a valid platform field.  This causes a failure of the type:

warning: package lsb-test-core-4.1.15-1.x86_64 is intended for a %{_target_platform} platform

When we detect an invalid platform, fall back and try to construct a new
platform name that may be valid based on the arch and os contents of the
package.  (This should only ever be needed by invalid or older RPM packages.)

+Enable platform tag matching workaround in OE.
+
+When installing some LSB packages the 'platform' field in the package
+appears to be invalid.  Instead of relying solely on the platform comparison
+we also want to generate a perceived platform based on the valid rpm contents
+of arch and os.
