Regression test portability: arequal-checksum
Building arequal-checksum on non Linux systems requires a few adjustments: - use __builtin_alloca() on all platforms - on systems without argp, get it from contrib/standalone-argp (this requires adding cflags support to the build_tester function) - FTW_ACTIONRETVAL option to nftw(3) is GNU libc specific, work around if it does not exist. - md5sum is Linux-specific. Use md5 -n on NetBSD and md5 -q on FreeBSD/Darwin - Use 'cc' as synonymous for all compilers, it can behave as gcc/clang depending on which is default - cleanup tabs/whitespaces BUG: 764655 Change-Id: I9090c17da596fbf00fc1fbd7593163ce8cd3b84c Signed-off-by: Emmanuel Dreyfus <manu@netbsd.org> Signed-off-by: Harshavardhana <harsha@harshavardhana.net> Reviewed-on: http://review.gluster.org/8283 Tested-by: Gluster Build System <jenkins@build.gluster.com>
