# build.sh [OUTDIR]: build the binaries the tests need in OUTDIR (default: the
# current directory): scubed3, scubed3-crash (with -DSCUBED3_CRASH_TEST, see
# README), scubed3ctl and keystorectl from ../src, and jstat (unit test of
# juggler.c)
#
# the configure step of the main tree must have been run (config.h); extra
# compiler and linker flags can be given in EXTRA_CFLAGS and EXTRA_LDFLAGS
# (for libraries in a non-standard place); libfuse 3 is found with
# pkg-config
