Add the -D_GNU_SOURCE flag to KHDR_INCLUDES so that it is defined in a central location. Commit8092162335("selftests/harness: remove use of LINE_MAX") introduced asprintf into kselftest_harness.h, which is a GNU extension and needs _GNU_SOURCE to either be defined prior to including headers or with the -D_GNU_SOURCE flag passed to the compiler.
