[meta-ti] [PATCH] linux.inc: don't choke on missing defconfig in lzop dep

[Christopher Larson]

When a recipe is being parsed which will be skipped due to an incompatible
machine, no local defconfig will exist for the current machine. It seems 
that
the fetch localpath code doesn't error in that case, so we need to check for
an IOError on the attempted open. Without this, we can hit parse errors.
