gprofng: Skip jsynprog with a broken javac

On CET enabled Linux/x86-64 machines, one can get

$ javac simple.java
Error: dl failure on line 894
Error: failed /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.322.b06-6.fc35.x86_64/jre/lib/amd64/server/libjvm.so, because /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.322.b06-6.fc35.x86_64/jre/lib/amd64/server/libjvm.so: rebuild shared object with SHSTK support enabled

Set GPROFNG_BROKEN_JAVAC to "yes" only with a broken javac and skip the
jsynprog test with a broken javac.

	PR gprofng/28965
	* Makefile.am (GPROFNG_BROKEN_JAVAC): New.
	(check-DEJAGNU): Pass GPROFNG_BROKEN_JAVAC to runtest.
	* configure.ac (GPROFNG_BROKEN_JAVAC): New AC_SUBST.  Set to yes
	with a broken javac.
	* Makefile.in: Regenerate.
	* configure: Likewise.
	* testsuite/gprofng.display/display.exp: Skip jsynprog with a
	broken javac.
