testsuite: Fix pr119160.c for non-glibc targets [PR119862]

Testcase pr119160.c fails with symbol referencing errors for
`__cyg_profile_func_enter` and `__cyg_profile_func_exit` on non-glibc
systems.

This patch adds empty definitions for `__cyg_profile_func_enter`
and `__cyg_profile_func_exit` in order to prevent those errors.

	PR testsuite/119862

gcc/testsuite/ChangeLog:

	* gcc.dg/pr119160.c: Added empty definitions for
	`__cyg_profile_func_enter` and `__cyg_profile_func_exit`
	functions.
