scripts: refine static linking check to better guide the user

The current mechanism to check if static linking is possible, and the mesage
displayed on failure, can be puzzling to the unsuspecting user.

Also, the current implementation is not using the existing infrastructure,
and is thus difficult to enhance with new tests.

So, switch to using the standard CT_DoExecLog infra, and use four tests to
check for the host compiler:
- check we can run it
- check it can build a trivial program
- check it can statically link that program
- check if it statically link with libstdc++

That should cover most of the problems. Hopefully.

(At the same time, fix a typo in a comment)

     7 GCC 4.3 changed the location of some of the header files.  I don't

     8 understand why you'd be getting these errors while building GCC since

     9 it provides them.

    10 

    11 With regard to GLIBC, Roland checked in some changes so that the GLIBC

    12 build system could find the new locations of the GCC provided header

    13 files.
