Bugzilla Bug 135023

two systems, one 32bit, one 64bit, both running ~$ARCH. 32bit build works
without issue; 64bit build bombs out pretty much right off the bat:

Reopen if it's still an issue, but I'm very certain it's your cflags, as other
users can compile it fine on amd64.

not arch specific problem. autofs isn't parallel make safe. I think it hits
some kind of race condition here. if mount.h isn't completely generated when it
compile listmount.c, it will fail with above error. with the same MAKEOPTS=-j5,
sometime it works and sometime it doesn't. Since it doesn't take loong to
compile this package. I'd proposed to force -j1 on it.

I spotted the race, and fixed it properly.
