perl-cross: Correct function signatures in configure_func.shyoe/mut
There are latent issues in function detection which were succeeding due to compiler being lenient, but this is fast changing e.g. clang-15 has turned the -Wimplicit-function-declaration into error which ends up failing these tests and rightly so. Therefore try to improve the tests to have proper prototypes known during compilation Signed-off-by: Khem Raj <raj.khem@gmail.com>

+Subject: [PATCH] configure_func.sh: Add _GNU_SOURCE define and function
+ signatures
+
+Modern compilers are getting stricter about include paths and function
+signature being known duting compilation e.g. clang-15 now errors out if
+a function signature is not found
+
+try.c:1:18: error: call to undeclared function 'getspnam'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
+
+This causes the test of function to fail even though the function is
+available in libc. Therefore try to add proper include headers which
+define these functions and also define _GNU_SOURCE in every test
+since some of GNU/Linux funtions e.g. accept4 are guarged by this define
+
