[PATCH 1/3] sanity.bbclass: Check for the known broken version of make

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

See GNU Savannah bug 30612 -- make 3.82 is known to be broken.

A number of vendors are providing a modified version, so checking
for just the version string is not enough.  We also need to check
if the patch for the issue has been applied.  We use a modified
version of the reproduced to check for the issue.
