detection of functional openat() for usage inside getcwd.c

Hello,

getcwd.c uses *at() function family iff AT_FDCWD is defined.
This approach does not work on GNU/kFreeBSD - FreeBSD kernel + GNU libc.
The kernel does not provide needed interfaces, and therefore glibc
provides only stub version for function from *at() family.
But the AT_FDCWD is declared and getwdc.c uses only native i.e. openat().

Please, could you change detection whether really use *at() function family in getcwd.

Many thanks

Petr
