Add a test for profiling static executable
The function, main, is added to profiling output of static executable which must link against gcrt1.o. * Makeconfig (+link-static-before-libc): Use the first of $(CRT-$(@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. * gmon/tst-gmon-static.c: Likewise.
