This type of functionality would be great. For example, I am building this for Android and I only need basic parsing of radiotap and IP. However, with all of the other dissectors, this blows the size of libwireshark up (to what actually gets linked) to over 80MB.

Yeah initial version might use it, but it won't solve all problems, for example:
pop3s should force (at least compiling) of pop3 dissector.
It'd work with #ifdef-ing whole file (which I think is the most portable way of implementing it) with:
#if defined(CONFIG_POP3) || defined(CONFIG_POP3_SSL)
But I think it's good idea to show user that this dissector is forced by another dependency (in menuconfig it's shown as -*-),
and in future it'll be required to don't compile empty files.
Another problem is with generating register.c, cause dissector files are not preprocessered (or they are?).
