cc/gcc: pass the install prefix to the core passes

Currently, the discrimination on the core compilers prefixes depends on
the type of core compiler to build.

This is not correct, and the caller of the core backend should specify
the prefix.

     7 textrels are bad for forcing copy-on-write (this affects everyone),

     8 and for security/runtime code generation, this affects security ppl.

     9 But in either case, it doesn't matter who needs textrels, it's

    10 the very fact that they're needed at all.
