[PATCH] ld/testsuite: skip tests related to -shared when disabled

[Clément Chigot]

I didn't remove the hardcoded switch below as I'm not sure if some
platforms still want to skip these tests even if the shared support is
there. 

---

Call the helper function "check_shared_lib_support" to ensure -shared
is enabled before launching ld-shared, ld-elfweak and ld-elfvers.
This allows to catch custom targets explicitly disabling it.

ld/ChangeLog:

	* testsuite/ld-elfvers/vers.exp: Call check_shared_lib_support.
	* testsuite/ld-elfweak/elfweak.exp: Likewise.
	* testsuite/ld-shared/shared.exp: Likewise.
