New flag -XCClinker

[Boehne, Robert]

Hello,

I've found that -Xlinker and -Xcompiler -Wl, && -Wc,
were not quite enough.  The problem appeared when I
needed to make sure a linking flag was passed to the
C++ compiler driver as-is.  Without this patch, the only
way I could get these flags in the right place was to
set CXX to "$CXX -flag1 -flag2" and that broke a few
configure tests.  In general, I think non-C compilers
need a flag like this when it should be passed at link
time to the compiler driver.

This patch adds the flag -XCClinker which behaves just like
-Xlinker but does not append ${wl} to the flag.  Documentation
is also updated.  I've tested the patch, and found no regressions.

Ok to commit?
