244acf3a4b Link with -rdynamic instead of -Wl,-export-dynamic.
Recent versions of the OS X linker support this but follow the existing
OS X linker convention of using an underscore in the option name, i.e.,
-export_dynamic. Rather than changing our configure scripts to check for
that alternate spelling, it is simpler to just use the compiler's -rdynamic
option and let it deal with translating that to the appropriate linker
option. One potential disadvantage of this approach is that the compiler
will typically ignore -rdynamic on platforms where it is not supported, so
the HAVE_LINK_EXPORT_DYNAMIC in config.h will not necessarily show whether
that option has any effect or not. I don't see any in-tree uses of that
macro, so I'm assuming it is OK.

8b37637b7f Strip extraneous information, if present, from the linker version string on
Mac OS X. Patch by Fabian Groffen, with a slight tweak by me.

ee0f32d723 configure: Add detection of the linker version string.
- Review appreciated, as long as you understand that I understand that this is
   a horrible hack.

da612d6226 -retain-symbols-file is not what it seems. Update the makefiles
and configury to use --version-script.

39ed6789c5 Fix an autoconf bug: The second argument to AC_LANG_PROGRAM is code that
gets placed inside a main function, and should not itself be a main
function. This is silently hidden in GCC-hosted builds because the
inner main looks like a nested function declaration, which GCC supports.
In builds with compilers which do not support nested functions (by default),
this was causing an error, which caused these autoconf checks to fail, 
leaving their options disabled.

This fixes test/Feature/load_module.ll on x86_64-unknown-linux-gnu
llvm-gcc selfhost builds, among other things.

This also includes a regenerated configure, as the diff is small and telling.

e05f609b61 Add an autoconf check for -retain-symbols-file and conditionalize
use of that option with it. This eliminates an imprecise "Linux"
test, and should help support old versions of gold.
