Make sslscan target non-phony

[jjlin]

Since sslscan is a real file, it should be removed from the .PHONY list
so that make static install won't try to build a non-static version.

Any particular reason you haven't merged this yet? In #68, you wrote:

Doing it in bash seems like a bit of an ugly fix, but I couldn't see a nice way to do the check natively in the Makefile

Making sslscan a non-phony target and letting make create that file as necessary is how that check is done natively.

The sslscan target was originally marked at as pnony in the PR that introduced static building. The problem with marking it as non-phony is that it means that if (for example), you run make, then if you run a make static it will see that sslscan already exists so won't rebuild it (so you'll still have the dynamically build version), which isn't desirible. It's a pain if you have to keep running make clean, because that also blows away the compiled OpenSSL stuff.

I needd to see if there's a nice way to allow both make and make static to work properly with a non-phony sslscan - although I have a feeling it will involve some more ugly bash code :/
