On my machine, this cuts symbol loading time (breaking at main) from 45 seconds
to 17 seconds (with gdb v8.3.1).

Now works like this now:
Given a LibraryPath
/some/path/to/engine/root/Engine/Binaries/Linux
Split the LibraryPath to everything but the root path to the engine:
Engine/Binaries/Linux
Given the OuputFile.Location.Directory for the module being produced
/some/path/to/engine/root/Engine/Plugin/Foo/Binaries/Linux/
Make relative from the root engine dir against the OutputFile.Location.Directory to produce how many ../ are needed:
MakeRelative /some/path/to/engine/root To -> /some/path/to/engine/root/Engine/Plugin/Foo/Binaries/Linux/ = ../../../../../
Now just combine ../../../../../ + Engine/Binaries/Linux as our new RPath. So now at runtime we can use this relative path to figure out where the *.so we depend on in that dir exists

When linking shared libs (DSOs) under Linux, we need the -shared-libsan option. This will cause us to load the libclang_rt.asan-x86_64.so, etc and not static link so we need to add the path to the executable rpath.
https://github.com/google/sanitizers/issues/1086https://www.gitmemory.com/issue/google/sanitizers/1086/509784249
Add linux sanitizer information to build details if set. Should look something like this:
------- Build details --------
Using system toolchain.
Using clang (/usr/bin/clang++) version '8.0.1' (string), 8 (major), 0 (minor), 1 (patch)
Using bundled libc++ standard C++ library.
Using lld linker
Using llvm-ar : /usr/bin/llvm-ar
Building with: AddressSanitizer
Using fast way to relink circularly dependent libraries (no FixDeps).

We now only check for and use the system compiler if "-ForceUseSystemCompiler" command line is passed
Also don't default to epic compiler if -ForceUseSystemCompiler specified and we can't find the system compiler
