link with "libssp" on *-sun-solaris systems

[jclulow]

LLVM will insert calls to the stack protector functions
"__stack_chk_fail" and "__stack_chk_guard" into code in native object
files. Some platforms include these symbols directly in libc, but at
least historically these have been provided in libssp.so on illumos and
Solaris systems. Include "-lssp" in the arguments to the linker when
building for those targets.

Hi folks. I'm not really sure what to do about this failure from CI.

[TIMING] Tidy -- 18.210
Build completed successfully in 0:00:41

Cloning into 'rust-toolstate'...

KeyError: u'rustc-dev-guide'

It looks like at least some of the job(s) were manually cancelled by @alexcrichton.

OK, I've had a look at the contents of the illumos/Solaris sysroot in dist-various-2 and it's unfortunately missing libssp.so.0.0.0 on both platforms. I'll push ahead with creating a proper dist-x86_64-sun-solaris image first, with a more complete sysroot that can perform full dist builds, then circle back here.

Apologies for the trouble!

[mati865]

@jclulow you should discuss that with infra first. CI has limited capacity and adding new builder is rarely accepted.

☔ The latest upstream changes (presumably #71162) made this pull request unmergeable. Please resolve the merge conflicts.

[jclulow]

@pfmooney and I have decided to focus our effort here entirely on the new illumos triple, which has now integrated as #71145 and which includes this functionality for that platform.
