[OE-core] [PATCH 1/1 v2] sanity.bbclass: Check for the known broken version of make

[Mark Hatle]

Just an FYI -- this fails (correctly I might add) on many Fedora systems.  It 
turns out that their version of make 3.82 is only partially patched.

The specific check we look for looks for two different problems.  The first is a 
target that includes target(dep1 dep2 dep3).  The second is a target that starts 
with leading spaces.

 From what I can tell, most Fedora 3.82 versions are patched for the first 
problem, but not the second.

There are other problems with 3.82, but this patch appears to detect the most 
broken of 3.82 versions in common use.

(And no, this is no longer an RFC.  I think this is the correct patch!)
