Subject: [PATCH] core: allow having a list of "cmake" candidates

Add the BR2_CMAKE_CANDIDATES variable, containing a list of candidates
to check and use as BR2_CMAKE, if possible.

This allows using "cmake3" on CentOS 7, whose default cmake corresponds
to version 2.8.12. Example:

    $ make BR2_CMAKE_CANDIDATES="cmake cmake3"
