With the attached patch, "gcc -Wl,--disable-large-address-aware ..." 
works as expected. Documentation update is missing.

It would probably make sense to add a --enable-large-address-aware 
option as a synonym for --large-address-aware to keep enable/disable 
options consistent.

There is a similar issue with --tsaware. It is enabled by default in 
spec file but cannot be disabled in gcc command line. I don't know 
whether there is a need for --disable-tsaware.
