Support single digit GCC version

On Fedora 26, "g++ -dumpversion" displays "7", instead of "7.1.1".
Update selective.exp to support single digit GCC version.  Also
remove duplicated [4-9] version check.

	* testsuite/ld-selective/selective.exp: Support single digit
	GCC version.

(cherry picked from commit 61a0857c0fb512ce6a2ba4315a37fcce744f6045)
