Currently, 'linktest' in libuafs is built with a weird custom rule
that specifies several various CFLAGS and LDFLAGS, etc. One
side-effect of this is that linktest is built without specifying -O,
even if optimization is otherwise enabled.
Normally nobody would care about the optimization of linktest, since
it's never supposed to be run, but this can cause an error when
building with -D_FORTIFY_SOURCE=1 on some systems (such as RHEL7):
In file included from /usr/include/sys/types.h:25:0,
from /.../src/config/afsconfig.h:1485,
from /.../src/libuafs/linktest.c:15:
/usr/include/features.h:330:4: error: #warning _FORTIFY_SOURCE requires compiling with optimization (-O) [-Werror=cpp]
# warning _FORTIFY_SOURCE requires compiling with optimization (-O)
^
cc1: all warnings being treated as errors
make[3]: *** [linktest] Error 1
For now, to fix this just include $(COMMON_CFLAGS) in the flags we
give for linktest, so $(OPTMZ) also gets pulled in, and building
linktest gets a little closer to a normal compilation step.
