abseil
Try to fix #841
As I see in #841 clang with undefined sanitizer with libstdc++ can't be fixed with additional compile/link option
I don't think this change is desirable. If you want to use UBSAN, you have to link in the required libraries.
I don't think libc++ required for clang ubsan. Without this patch clang with libstdc++ with ubsan is unusable, I think it's really annoying, and patch is simple, and don't affect others configuration
@derekmauro Why I can't use abseil with clang ubsan with libstdc++?
I don't think this change is desirable.
I don't understand why
This option cannot be directly set, so I think if exist some valid configuration that doesn't work with this option we want to disable option for this configuration

@derekmauro What is your version of gcc, clang, libstdc++?
If you are having a problem, you should be telling me how to reproduce it.
