Bug #12303: No rule to make target '.ext/include/i386-cygwin/ruby/config.h', needed by 'main.o' when ./configure TEST_COLORS=skip=43

I could not find any document describing
how to use TEST_COLORS environment variable in Ruby.
I could change the color of messages with ./configure TEST_COLORS=skip=43
and it finished successfully. However, after that, make results in an error.

$ ./configure TEST_COLORS=skip=43
    :
$ make
    :
gcc version 4.9.3 (GCC)
make: *** No rule to make target '.ext/include/i386-cygwin/ruby/config.h', needed by 'main.o'.  Stop.
$

I found this problem on Cygwin with gcc, Mac OS X with gcc,
Mac OS X with clang, and Linux with gcc (Ubuntu 14.04).
I found this problem both in ruby-2.3.0 and trunk (2.4.0dev).

I am sorry if I set TEST_COLORS incorrectly.

ifchange: ignore unmatch TEST_COLORS

• configure.in: check if succeeded in creating config.h.
• tool/ifchange: ignore failures when TEST_COLORS unmatched. just
  use the default value if expected name is not contained in it.

Thank you for the fix, Nakada-san.
Workaround for ruby-2.3.0 may be ./configure TEST_COLORS=pass=32:fail=31:skip=43.
