getconf: only use specs that are available
On older glibc (like 2.7), the _SC_V7_* symbols are not defined, making the build of current uClibc fail on Debian Lenny systems and other systems using a fairly old glibc. So we make sure to only use the specs names that are defined by the host C library.
