H.J. Lu a4777c46af Add a test for profiling static executable
The function, main, is added to profiling output of static executable
which must link against gcrt1.o.

	$(CRT-$(@F)) and $(csu-objpfx)$(static-start-installed-name).
	* gmon/Makefile (tests): Add tst-gmon-static.
	(tests-static): Likewise.
	(CFLAGS-tst-gmon-static.c): New.
	(CRT-tst-gmon-static): Likewise.
	(DEFAULT-LDFLAGS-tst-gmon-static): Likewise.
	(tst-gmon-static-ENV): Likewise.
	(tests-special): Likewise.
	($(objpfx)tst-gmon-static.out): Likewise.
	(clean-tst-gmon-static-data): Likewise.
	($(objpfx)tst-gmon-static-gprof.out): Likewise.
	* gmon/tst-gmon-static-gprof.sh: New file.
