Centos 7 has glibc 2.18 and nss-native build fails due to implicit
declaration of function putenv during build. This is because of the
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
putenv(): _XOPEN_SOURCE
|| /* Glibc since 2.19: */ _DEFAULT_SOURCE
|| /* Glibc versions <= 2.19: */ _SVID_SOURCE
and because nss coreconf/Linux.mk only defines
-D_DEFAULT_SOURCE -D_BSD_SOURCE -D_POSIX_SOURCE
So on such system with glibc 2.18, neither macro makes putenv()
available. Add -D_XOPEN_SOURCE for the Centos 7 and glibc 2.18
native build case.
