rust use very different compiler options from Clang/GCC, so it's clear what 
benefits a unified format can bring, if we consider that more established 
compilers want to prefer internal consistency and avoid introducing duplicate 
mechanism.
GCC uses specs files. There may be some obstacles introducing a new mechanism.
Clang Driver doesn't support specs files. We pick configuration files for now 
whose format isn't different from the traditional response files.

If anything, rust can make a decision to support Clang style configuration 
files.
