Define _GNU_SOURCE for glibc extensions
glibc does not declare a number of common, useful extensions such as
asprintf unless _GNU_SOURCE is defined. Define it early in the
configure process so that it is available for autoconf tests.
Defining _GNU_SOURCE unfortunately causes glibc to use the non-POSIX
version of strerror_r, which we now handle using the k5-platform.h
wrapper.
