I'm not so sure about this honnestly
The problem is that you don't know which linker gcc (or whatever CC is
being used) will call. That can be hardcoded inside the gcc spec file
for example if using a cross compiler.
I have hit the issue with libxml2 in different ways because I reused
that code in configure but I still don't know how to really address that
Using ld from $PATH might be a bit better in some case but it's really
not garanteed to work in all cases, taht's painful.
