configure: Fix libc version check
Testing for gnu_get_libc_version isn't quite right (available before
2.1), and the feature macros were already present.
The new test at least will fail for glibc < 2.1, but will pass on
non-glibc systems.
The buildsystem should be actually checking for some sort of compliance
barrier instead, but this is a start.
