Last part of changes regarding to libm-test.inc: addition

of method for separation which exactly testing function needed to run with
help of generated during make check header with series of conditional
definitions.

2015-05-14  Andrew Senkevich  <andrew.senkevich@intel.com>

    * math/gen-libm-have-vector-test.sh: Script generates series of macros
    for conditions in testing functions.
    * math/Makefile: Added call of libm-have-vector-test.sh.
    * math/libm-test.inc (HAVE_VECTOR): New macros.
