/usr/bin/ld: error: undefined symbol: main [r337834 -> r337903]

[Xin LI]

This was caused by r337852, but I didn't investigated further.

The problem is that we have a source file called 'moduli.c' in
crypto/openssh/ while the build target was moduli, and bmake seen
'moduli' in source tree as older than moduli.c, and decided to rebuild
it from source, while the two files are unrelated.

Cheers,
