#[start] doesn't work with cdylib

[wangbj]

It is useful to pass -Wl,-e_<entry> to the linker, even for shared libraries, it doesn't seem like #[start] can change cdylib entry address, if this is intended, is there anyway to change entry address for cdylib?

#[start] only affects which function will be called by the auto generated main function for executables. Using it to pass -Wl,-e_<entry> is wrong as that skips the initialization code of libc. You can pass -Clink-arg=-Wl,-e_<entry> to rustc when compiling if you want to pass this to the linker.
