Needs ReviewPublic

Summary

Such file can be set at configuration time through -DCLANG_DEFAULT_CONFIG_FILE
and is used if no other configuration is provided.

It allows package maintainer to provide per-distribution default flags like
default gcc toolchain, linker error script etc.

Great idea. Do you have an example of what the configuration could look like on a distro?
Merci!

I was thinking of `-Wl,--error-handling-script=/etc/clang/linker-script.sh` or something along the line. The initial goal would be to suggest installing the asan runtime if some asan symbols are missing.

@sylvestre.ledru Can you drop the picture?

Can you give an example of how this would be used to select the gcc-toolchain?

That would mean shipping a configuration file with a

--gcc-toolchain=/path/to/the/toolchain

Sure, this is one of the phab macro and I wasn't expecting it to be that big :)
