wscript misdetects availability of functions for conditional compilation (getpass, setegid, ...)

Description
The test program generated by waf for getpass is:
#include <unistd.h>
int main(int argc, char **argv) {
void *p;
(void)argc; (void)argv;
p=(void*)(getpass);
return 0;
}
which fails to compile with our debug CXXFLAGS due to the presence of -Werror:
['/usr/bin/g++', '-pedantic', '-Wall', '-O0', '-g3', '-Werror', '-Wno-error=maybe-uninitialized', '-Og', '-fdiagnostics-color', '-std=c++11', '-D_DEBUG', '-DHAVE_IS_DEFAULT_CONSTRUCTIBLE=1', '-DHAVE_IS_MOVE_CONSTRUCTIBLE=1', '-DHAVE_IS_MOVE_ASSIGNABLE=1', '-DHAVE_CXX_FRIEND_TYPENAME=1', '-DHAVE_PTHREAD=1', '-DHAVE_RT=1', '../test.cpp', '-c', '-o', '/home/davide/ndn-cxx/build/.conf_check_cb65f796106d255f157c14cc65e54028/testbuild/test.cpp.1.o']
err: ../test.cpp: In function ‘int main(int, char**)’:
../test.cpp:4:8: error: variable ‘p’ set but not used [-Werror=unused-but-set-variable]
void *p;
